RE: Database in C (Re: Msg 84363)
From: CHYDE To: FRANCALCRAFT

I’m sure someone else has already mentioned this, but I’ll tell you before
reading the rest of the thread . You don’t have to treat your .r files
as libaries, treat them as seaperate files to link. I don’t use cc (I
prefer to use my memory for other things ), but I’m sure you’ll be able
to link everything using the following command:

cc os9top.c os9search.r os9chdel.r os9enter.r keyword.r -l=/d2/lib/cgfx.l

The precompiler (cc) should compile the .c file to a .r file then link in
all the .r files on the command line and finally link to the libraries

(oops wrong key). As an aside a single .r file is not really a library and
so there is no reason to treat it like one. If you want you can merge all
your .r files together into a single file and treat that like a lib file.
Read page B-5 of the compiler manual for info about user defined libraries.
and pages 1-13 and 1-14 for info about using the compiler (cc1, cc should
implement the same features).

Hope this helps, some.

The idea _is_ good and noble, but kinda halts us “mercenary” lots…

On a BBS once, we got into a discussion about providing source with your
release. One guy said he would NOT use anything that did not have source.
I have released the source with one of my programs (“gfx3″ from way back
when..). But since then, especially in the light of the hassle that Carl
Kreider went through with unauthorized releases of “ar” (and he didn’t
even provide source, I don’t think), I have decided that it could cause
you problems if someone clobbered up your code and re-released it in your
name, so I’m not sure that I’m as much in favor or releasing code as I
once was.

Again, I can see the point of the restrictions on the GNU stuff, but if
I should release anything, even to the PD, I would still prefer to retain
control over what is done with the code, especially if I’m going to get
blamed for it. Of course, not releasing code still does not preclude
someone’s disassembling the code and working on it, but that would require
a capability in one that would indicate that he could produce good code in
his modifications.

powerbasic vs. Ultra C

powerbasic vs. Ultra C
From: PAGAN To: ALL

Out of curiosity I downloaded the benchmark programs that Frank Hogg offered
for his new PowerBasic compiler. I converted these programs to “C” and
compiled with Ultra C. I used no optimization (-o=0) and used the “csl”
trap library (-i). In each case, I tried to faithfully duplicate the
function of Frank’s original code rather than use any slick tricks to speed
things up. Where C doesn’t have an equivalent function, I used the nearest
I could think of. For example in “bench6″ below, Basic has the “str$”
function for which I substututed the C “sprintf()”.

The codes sizes for UCC listed below do not include the 47K overhead of the
“csl” trap library and the execution times should be considered for
information only; The test programs are do nothing loops that, in my
experience, don’t reflect the real world performance of a complex
application. Also, benchmarks don’t account for development and maintenance
time nor for “intangibles” like personal preference.

Test were done on a Delmar System IV with G-windows and screen saver
deactivated by putting the mouse cursor in the lower right corner.

PowerBASIC details?
From: JEJONES To: FHOGG

I’ve downloaded the files you uploaded about PowerBASIC, and I have a few
questions about the language.

– What data structuring facilities does it have (e.g. is there anything
analogous to the BASIC09 TYPE statement)?
– You say it supports separate compilation; does that mean that there are
actual functions with local variables? What’s the syntax for calling a
separately compiled unit, passing parameters (including structured types
if the language supports them), and returning results?
– What debugging facilities does PowerBASIC have? (All I saw mentioned
in the file was a listing of assembly language output with the PowerBASIC
source interspersed.)

If you could post or upload a sample of PowerBASIC code displaying some of
its features, that would help a lot. Thanks.

_gs_rdy() Question
From: DBREEDING To: ALL

Hey, Gang, I have a question. Why doesn’t the following work?

I have tried this both on my OSK and CoCo, and get similar results.
The program as written will continue to loop, keeping getting the “AT”
and “OK”, with some other gibberish. It seems to keep writing and reading
the modem.

If the while{} statement is not used, and The Alternate Method, commented
out, here, is used, if you write something to the modem, then you keep
getting a positive value returned from _gs_rdy(). If you do the for loop
without writing to the modem, you keep getting a -1 returned, which is
correct. But if something has been written, it looks like the pointer
is not getting updated, and, in fact, it seems that it keeps getting rewritten
to the serial port.. strange.. or am I overlooking something?

Note: this is the coco version, but, as I said, OSK seems to act the same
way. This here is just a test program.. but it still looks like it SHOULD
work. I’ve also tried time loop delays between reads, etc, but still
no luck.. I can’t see why it keeps sending to the modem..

#include
#include

int mdm;
char buf(30);
char cmd(10) = “AT\x0d”; /* try something else, too */

main()
{
int count, state;

if ( (mdm=open(“/t2″,UPDATE)) == -1)
exit(1);

write( mdm,cmd,3);

while ((state=_gs_rdy(mdm)) > 0 ) {
printf(“\x0a_gs_rdy()=%d Read()=%d “,
state, read( mdm,buf,state ) );
fflush(stdout);
write( 1,buf,state );
}

/* Alternate method */
/* if the above after the open() is deleted, _gs_rdy() returns
-1, but if the write() call is left in, it goes crazy */
for (count=1;count<10;count++ ) {
printf(“_gs_rdy()=%d\n”,_gs_rdy(mdm) );
} /* End Alternate method */

close(mdm);

Signals in UCC
From: PAGAN To: ALL

I recently posted a request for information re the signal() and
_os_intercept() functions in UCC. Here’s what I learned:

It’s not necessary to _os_sigmask() unless you need to clear or increnment
the signal mask.

To second parameter should be _glob_data which is initialized in cstart just
for this purpose. Microware overlooked this in it’s documentation

The process becomes:

void SignalCatcher(sig)
int sig;
{
/* process the signal */
_os_rte()
}

main(argc,argv)
int argc;
char *argv();
{
extern void *_glob_data;

_os_intercept(SignalCatcher,_glob_data);
}

BTW, using debug it looks like _os_intercept has less overhead than the old
intercept() function in the 3.2 compiler.

Thank for the information goes to Peter Dibble, A.B. Cohen Stuart and
Ruediger Nahm-Elstner (PEP Modular Computers).

signal handling in UCC

90638 12-NOV 14:33 Programmers Den
signal handling in UCC
From: PAGAN To: ALL

Does anyone know how to use the signal() and _os_intercept() functions in
Ultra C? I’m trying to get a transfer program working under OS9 & OS9000
and both calls are causing unexpected problems. I’m doing the development
under OS9/68000.

globally defined variables:

volatile sig_atomic_t
g_sigmodem=0,
g_abort=0;

path_id modempath;

Using signal():

void ModemSignal(sig)
int sig;
{
signal(sig,modemsignal); /* reset signal handling */
g_sigmodem++; /* set flag */
}

This worked fine in the short test program but blew up the main program with
when I returned from the put character routine:

S_PutC(ch)
int ch;
{
u_int32 size=1;
u_char khar=ch;

_os_write(modempath,&khar,&size);
return;
}

Sometime the program quit with an error #103 (address trap error) or locked
up or went out and stomped all over another module. When I move the signal
reset into the body of the program the error dissappears but resetting the
signal handling from within the main program is not going to work with real
world signals. I suppose I could mask interupts in the signal handler and
unmask after checking the flag but that seems a little clumsy to me.

I tried using _os_intercept(). The prototype is:

error_code _os_intercept(void (*)(), void *);

I can set up a signal handler easily enough:

void SignalCatcher(sig)
int sig;
{
_os_sigmask(1); /* mask signals */
switch(sig) /* set appropiate flag */
{
case SER_SIG:
g_sigmodem++;
break;
case SIGINT:
case SIGQUIT:
g_abort++;
break;
}
_os_sigmask(0); /* unmask signals */
_os_rte(); /* go back */
}

but where does that second void * come from? Under OS9 I’ve tryed passing
it as 0 and as “void *void_ptr” which will compile but _os_intercept()
returns an error #225 (Bad Parameter) and doesn’t set any intercept.
Passing it as an address of a global variable (&g_sigmodem) won’t compile in
extended ANSI mode – I haven’t tried that with -bc set.

The program works fine with the old intercept() call but that requires
linking with the -bc flag and there is no guarantee that Microware will
continue support for the backward compatability mode.

Piped input in Basic09

Piped input in Basic09
From: THETAURUS To: ALL

Does anyone have any advice on having my Basic programming
determine when the input it needs comes from a piped statement? I’m a
little confused on how to set this up.

The program in question is my Protector utility which I have
brought up in here many times before(this is my learning program
). I have to option parameters set up called option1 and option2. Here
is how the command line is set up…

‘Prot -(f),(s),or(?), and/or (v) (filename)’

On the above, option one is the ‘-’ with either ‘f’ or ‘s’ or ‘?’
following it, plus the verify option ‘v’ is optional and can be
appended to that. All that makes up option1. If you pick ‘prot -f’
with the ‘f’ meaning that input will come from a text file, it then
goes on to read option2, which will be the filename of the file with
the input. The ‘s’ option btw is so that you can read the the
filenames necessary from keyboard instead of the (f)ile.

With that explained, here are the possible command lines, to
clarify.

‘Prot -sv’ will get the filenames for prot from the keyboard and
will verify by asking you ‘Are you sure?’ before deleting any file.

‘Prot -s’ same as above except, it will not verify and will
delete automatically.

‘Prot -f Filname’ Will delete all filenames in current directory,
except for those listed in the input file as option2(filename).

‘Prot -fv filename’ same as above except it will verify each file
before deleting for the added safety.

Now I would like to make it possible to allow the program to read
a list of filenames to protect from a piped command such as:

‘ls!Prot’

Does anyone have any advise on how to set the parameter options
up in order to read piped input? This is my first time doing it.

Hi all, got one fur ya thats got me a bit puzzled. I grabbed the file
blobstop_v10.ar from chestnut last nite, a file which purports to be
the actual, we’ve been looking for it for 8 years now, blob killer.
Well, after splitting up the kernel and applying the patches to both
Boot and the disto cc3disk, I attempted to use “merge” to re-assemble
it. 7 flippin times! Each and every time, the os9p1 was trashed for
about 50 bytes starting at offset $D3F into the kernel file it made.
I screwed around for a couple of hours with it. Finally, in desperation,
I made the new kernel with “cpa” one file at a time for all 5 files
that are generated by my own vfy ed 11. That one vfy’d ok, and its
working right now.

Has anyone else ever had such a problem with merge? Edition 5, crc=6AD7A5

Just curious, its never done anything like that before, but it was
absolutely consistent in where it messed up the output file this
one time. 6 times that is.

Syscall+Basic09
From: CPERRAULT To: ALL

I am reading (yet again) the tech section of the OS-9 Level Two
manual and am trying to make sense of a lot of the syscall stuff I was
trying to understand before. Online forums are really the only place I
can get further information relating to this. The Tech manual makes a
great reference section, but does not, as I said before, supply
anything to the novice who needs to understand more about how syscall
works before attempting too much. I am just listing some
miscelleaneous questions here that are popping up regarding syscall.

1) There are many prefixes to the calls, which causes confusion
as to what goes with what else. For instance there are File Descriptor
related calls(FD) and Path descriptor calls(PD) in the RBF part. What
is the difference between these. Is there any relation between these
and the other calls such as those that begin with
“V.”,”IT.”,”F$”,”I$”, etc…

2) What is the Path number, which is normally option letter ‘A’
in the calls I read, associated with? What’s it for?

3) Do you pretty much have to have a knowledge of Assembly
Language in order to understand System calls?

In David Breedings reply to me, where he supplied me with the
undocumented(can you believe it) SS.FD call, it goes as follows:
A=path #(again, what would that be?)
B=$0F (wouldn’t this already be specified in ‘Run Syscall’
command parameter?)
X=ADDR(buf) (I imagine in my case of filename, the variable
‘Fname’ would go in the ‘buf’ section?)
Y= # of bytes to read (How does one know?)

Sorry about the unlimited amount of ignorance here, but it seems
no matter what,I still wind up lost. David’s previous message did make
things look a little easier, but I was still pretty useless when it
came to applying it. Does anyone see where I’m coming from?

From: JEJONES To: CPERRAULT

> Can someone point me to some referance material related to System
> calls and how to use them from Basic09(syscall)?

Well…here’s as good a short description as I can manage:

If you look in the OS-9 Technical Manual, you’ll see for each system call
a description of what the system call expects to see in the CPU’s registers
coming in, and a description of what the system call puts in the registers
before you get control back. The BASIC09 syscall procedure takes as its
parameters the following:

1. an integer number that corresponds to the system call you want to
run

2. a structure that contains an image of the CPU registers

What syscall does is create code that does the system call you want,
copy the contents of the structure into the CPU registers, executes
the system call, copies the contents of the registers after the system
call completes back into the structure, and returns.

So…if you want to use the syscall procedure, you have to look up the
system call, find the number that corresponds to it, set up the input
parameters, run syscall, and then retrieve the output parameters from
the structure you passed syscall to get the results. (You’ll want to
check the condition code flag image to tell whether it succeeded or
not.)

What you need is the “SS.FD” getstat call, which was omitted from the
tech manual.. From the data I have scribbled in it goes as:

SS.FD function code = $0F reads file descriptor into mem
dunno if it works as setstat or not.
A = path #
B= $0F SS.FD
X= ADDR(buf) predefined buffer for file descriptor
Y= # bytes to read

I assume you know how to set up the SysCall function. When you get it,
you check the FD.ATT byte, say you name it FD_Att:

Um3Play vs Nitros9

Um3Play vs Nitros9
From: WDTV5 To: UMUSE 4.10 U (NR)

This file goes with Umuse3, version 4.10, specificly with the UM3Play
module of that release. Apologies are hearby offered to Mike K. for
hacking his code so quickly.

Running under a Nitros9 system, the baud rate of the seriel timer in this
module is about 36.5 kbaud. Obviously this isn’t going to work when the
devices on the other end of the bit-banger cable are expecting a feed
reasonably close to 31,250 baud, the midi specification speed.

To restore operation of the bit-banger midi driver, grab your copy of
dEd and get sector $11 of Um3play on the screen. At offset $7D in this
sector you’ll find an $04 between a $C6 and a $12. This is the value
loaded into the B register and subsequently decremented to zero to
establish the correct bit timing. Changing the $04 to an $06, writing
the sector, and verifying the file will restore the timing to around
31,500 baud, close enough for my two casio keyboards to run flawlessly.
I tried a $05, but both keyboards rejected that approximatly 33 kbaud,
and they both rejected an $07, about 30 kbaud. so the $06 is as close
as we’re gonna get.

I hope this helps the Nitros9 users who also have Umuse3.
Cheers all, Gene Heskett, WDTV5@delphi.com

program update
From: CPERRAULT To: DBREEDING

I’m just bringing you up to date on what happened with the
program since I last talked to you. I did change the command line to
put the ‘,’ between the two quoted parameters and it did return the
filenames from the text file. Now my next problem was, it would return
all those files, but keep returning them over in over again. What I
was doing was, I had a for/next loop(which I probably didn’t need
since I was getting the names from a file, not keyboard) that kept
count on the files coming in. Problem? It was on the OUTSIDE of my
While/do/endwhile loop, instead of the inside! At least this one was a
simple solution. The good news is, I’m just about done. I have one
more bug to work out, which knock on wood, looks like I will have
fixed today. Then I will just clean up the code and then change the
parameter structure. I’m gonna make it so that instead of having to or
three different variables, I’ll combine them all into a complex data
type, so they don’t have to be seperated with commas. After that, I’ll
doc it up,LZH it and get it into the database so I can start on my
next program.

New programming trouble
From: CPERRAULT To: ALL

Ok, I have no begun to add the -f option to the ‘Protecter’
program I am writing and have run into a little problem. The command
line argument ‘-f’ is the option to have the program read the
filenames in from a file containing all the names. I call my test file
‘filelist’ and I used ‘ls >filelist’ to create it.
What happens is when I run the program(run begmain(“-f
filelist”)) the program just hangs and does nothing until I press
break. Here’s the new portion of the program I wrote to read in the -f
arg.

IF option1=”-f” OR option1=”-F” THEN
OPEN #diskpath,option2:READ+dir
FOR count=1 TO 100

WHILE NOT(EOF(#diskpath)) DO
SEEK #diskpath,length*count
GET #diskpath,name
EXITIF name=”" THEN
CLOSE #diskpath
GOSUB 20
ENDEXIT
PRINT name
GOSUB 30
newname(count)=temp
ENDWHILE
NEXT count
CLOSE #diskpath
(* ————————————–
ENDIF

From using Debug, I typed ‘print option1′ with option1 being the first
parameter read in from the command line(“-f -s or -?”) and it returns
‘-f’ saying that -f is the value of option1. Ok great, so I try to
verify by turning on the tracer(tron) and checking each of the ‘while’
and ‘if’ statements relating to option1. It returns all of them false
INCLUDING ‘-f’ which is opposite of what the Print Option1 tells me.
Also when I list it, the ‘*’ shows that the program is stopped at the
‘If option=”-f”…’ statement.

Does anyone have any ideas what might be causing this?

mm/1 screen
From: LARRYOLSON To: ALL

Could someone tell me how to get the pixel data from an MM/1 kwindow
screen ?
The C routine that I have been trying, is either wrong or I’m not up
on how the data is stored in memory.
For the test, I open a type 3 320×208 256 color window. Then using SetDPtr
I set the pointer location to 4,0 then I draw a line from there too 4,15.
Now what throws me is, that this type window should use 8 bits per pixel,
which means that if I get the screen start address using _gs_scinfo, and print
out the first dozen or so bytes, all the bytes should be the same(screen is
cleared), except the 5th byte, but when the test is run, it is the 3rd byte
that is changed.
Trying different locations:
screen x location byte changed
5 3rd
6 4th
7 4th
8 5th

This appears to me to be 4 bits per pixel, where are the other 4 bits ?
I am opening a window as a type 3, with the following:

Wpath2 = open(“/w”,3);
DWSet(Wpath2, 3, 0, 0, 40, 26, 255, 1, 1);

and getting the screen info with:

_gs_scinfo(Wpath2, &sc);

This has me stumped

BASIC09/Microware BASIC INT function

I was taking a look at a BASIC09 program in the latest *UpTime*, and in the
process of modifying it, I tripped over something that I figured is worth
passing along to others.

I was trying to move some coordinate conversion into a call to gfx2 (bgfx
for those of us with MM/1s), and figured I could turn the moral equivalent
of

xs := x0 + mx * x
ys := y0 + my * y
rs := mr * r
RUN gfx2(path,”circle”,xs,ys,rs)

into

RUN gfx2(path,”circle”,INT(…),INT(…),INT(…))

replacing the ellipses with the right hand sides of the assignments
to the corresponding variables (which were declared integer, of course).

BLAMMO! It barfed–but why? INT() returns the greatest integer less
than or equal to its argument, doesn’t it?

It finally occurred to me–yes, INT() does return that–but it returns
it as a REAL! I changed the INT() into FIX(), and all was well.

Kind of subtle, eh?

Opinions herein are solely those of their respective authors.

Latest in Basic problems
From: CPERRAULT To: ALL

Well here’s yet another update of how far a haven’t gotten with
my program. Gene(wdtv5) mentioned stripping the high bit on the last
byte and terminating the string with an $FF marker. Well I THINK I
stripped the bit, if stripping means lowering the bit value to where
it should be, at -128. I did it with the following statement:

name:=name+CHR$(Land(fname.filename(count),$7F))

And then I add the following statement after it:

Name:=name+chr$($FF)

Which I was hoping would mark the end of string properly. I have
still gotten no change in behavior from the program tho I have
tried quite a few other methods I can’t remember taken me so long to get back>, but they either produced the same
results or more disasterous results, such as only printing only the
last character in the filename, because of the way I did certain
statements. Certainly not completely DISASTEROUS but those results
only took me further off track. I’m assuming the reason I’m getting no
difference from the program is because I am applying the end of string
marker wrong. Maybe Name:=name+chr$($FF) is completely wrong?
Unfortunately this is the only way I can think of for doing it. Does
anyone know another way, and also, does anyone know where I might be
able to find some source code that does a job similar to what I am
doing? I can’t seem to find much in the way of Basic source here on
Delphi.

CoCo/OSK C compilers

CoCo/OSK C compilers
From: DBREEDING To: ALL

Here’s a little “feature” of the MW OSK C compiler I _BELIEVE_ I’ve
stumbled across. It could be common knowledge, but I’d never heard of
it myself. Seems that with a structure, from what I can determine, a
block of characters joined by an int, float, and ???, will have a
character added if the total for that blockof characters is odd. This
won’t hurt the program, but would cause problems in sharing files with
systems that don’t do this. I found this by trying to port a prog from
the coco to OSK. I was looking for int’s, but was surprised in the
filesize incongruity with structures containing only floats & chars. It
seems that the following will result;

* char a1(x);char c1(y);int b1 : if a1+c1=odd, one byte added, same
* if int b1 before the two.
* char a1(x);int b1;char c1(y) : if EITHER a1 OR c1 = odd, one byte
* added, if both odd, 2 bytes added.

* sizeof() reports correctly the actual size, reflecting any
* additional bytes added. If this is news, and anyone wants to
* play around with it, here’s a little routine for it.

struct { /* Play around with the order of the elements…*/
char a1(24);
int b1;
char c1;
} S1;

char a2;

main()
{
printf(” Size of S1 : %d\n”, sizeof(S1) );
printf(” Actual Size : %d\n\n”, (int)(&a2)-(int)(&S1) );
printf(” Totals of els: %d\n”,
sizeof(S1.a1)+sizeof(S1.b1)+sizeof(S1.c1) );
}

Another difference between the CoCo and the OSK compilers, although
insignificant, I suppose, is in mktemp(). The OSK mktemp checks the
directory for a unique tmpfile name, probably doing an “Open”. It exits
with Error #216 in “errno” – Coco doesn’t. I like to end a program
with “exit(errno)”, which looks kinda messy. Guess I’ll either have
to cleanup after mktemp (and others???) or do an exit(0) .

C question
From: ALWAGNER To: COLORSYSTEMS

I am currently involved in translating an engineering program written
in Q-BASIC into C. This is then to be compiled and run on an Intel 486
based system running UNIX. Since that last “foot in mouth” episode, I
have gained a great deal of respect for your C programing abilities and do
not wish to create a similar problem to the one that started that thread,
that is running out of stack space and/or memory. I am developing the
translation on my Lvl II Coco3 using Ansifront to allow ANSI C to be used.
My question is that since this has the potential for becoming a large
program by Coco standards, is there a way to “chain” programs together as
is done in BASIC or to say it another way, to call another seperate
program into memory, pass parameters to it, have it execute, and have the
called program pass info back? I think I understand function calls, but
aren’t they part of the calling program, as far as memory is concerned,
once the compiling has been done? The idea here is that no one program
would require more than 64k. The solution should be something that could
be carried over to the eventual platform for this endeavor which is the
above mentioned Intel 486 running UNIX. Thank you for your time and
consideration of this question.

Please, bear with me as now I am confused on something I thought I understood!
I thought if you used the preincrementation the equivelent would be:

while(exp2)
{
exp3;
statement;
}
Where as if post incrementation were used:
exp1;
while(exp2)
{
statement;
exp3;
}
In both cases, the exp3 is executed BEFORE the conditional is evaluated the
SECOND time, but where it is evaluated in relation to statement is what is
important here. If I am wrong, then why is the guy’s original program crashing?

The actual numbers he used to index his array were ok, but I maintain that
because he used preincrementation, the index actually went one past the
conditional on the last pass.

I recall looking at the code as it flew by and noting that in doing the
compare, the code shown did the toupper function ok, but did NOT have any
provision to handle the fact that as it comes off the disk, the first bit
in the last character of the name is set high. In order for the compare to
find them equal when they are, the code should strip that bit, and then
terminate the string with a basic09 “end of string” marker, an $FF hex.
Whoever that was, give it a try after plugging in the code to handle that
and I’ll bet it’ll work as you intended. Cheers, Gene

“push” or tie with regard to original bet and player gets original bet
back; if player does not have 21, then player loses original bet (dealer
automatically wins)

Programming in C
From: MROWEN01 To: ALL

I need some help with ‘C’ on the Coco 3. I am diving into writing some
programs, one because I need the programs, two because I want to leanr C. I
haven’t done anything elaborate yet. I have been working with C in both DOS
and UNIX environments up to this point. I prototyped some code under DOS, but
als, it will not be portable to UNIX or OS9. DOS compilers support the
getch function. This is the same as an inkey$ function in Coco basic. You
press a key and program flow continues. How do I duplicate this function under

Microware C or UNIX C? I tried to use getchar and getc under UNIX, but they
still require a carriage return. If someone could enlighten me….

The code under UNIX that I tried was :

key = getc(stdin);

even this !

key = fgetc(stdin);

NO LUCK! I need to write some terminal based apps for my Coco 3, and C seems
to be a good way of doing it. Anyone who has written in C on the Coco; If
you can give me tips or point me to patches and libraries you would recommend
I would appreciate it. I will upload what ever code I manage to hack.

Thanks.

Multivue
From: CURTPANTLE To: COLORSYSTEMS (NR)

Zack,

I found my recent reply to you was garbled – since then I found that three
“#define”‘s near the end of stdmenu.h had a “\” and a CR. When I deleted
these, it compiled fine.

Also, if anyone else is working with Multivue for the first time (I just got
it 2 weeks ago), the MV manual says to comile the C source to a .r file;
then link cgfx.l, clib.l and sys.l in that order. You have to put clib.l
first in the linkage order, otherwise you get a linker fatal error.

In addition to header and library files, I still need menu and window
descriptors and mouse code. Seems like a lot of work to point and click,
but I guess the hard part is putting it together for the first time. On
the plus side, MV works as advertised and I figured out how to write the
AIF’s to start several apps from MV.

Protector Program Update

Protector Program Update
From: CPERRAULT To: ILLUSIONIST (NR)

Hi again Mike, long time no see. I’m just writing to update you
on the latest progress I have made with my Protector utility project I
told you about before. And of course, I have questions about my latest
non-feature. This is also aimed at anyone else in forum who may
have some clues, and a little time to check the source, or run it in
from basic09. Since hooking my fathers printer to the Coco, I have
started working on my programming projects once again not having the printouts. I don’t care for having to constantly switch
through windows to compare code>. I have since fixed, as far as I
know, all the problems I was reporting before. Of course it’s been
about a week or two, so I already forget what those problems were I
was having, but it was a matter of modifying a loop structure a
certain way that did the trick. I couldn’t quite understand why the
fix I did worked already had, but since it worked…>. I should be keeping printouts of
the old source so I should remember exactly what those questions are
so I can post to all here, just to better understand things. Anyhow,
that’s not what I’m here to ask about.

For the most part, I have MOST of the program done. Once I get
through this latest glitch, I will just add a couple more features I
am hoping to add, which, knock on wood shouldn’t be
too much trouble. Just for a quick rundown for those who don’t know or
remember the purpose of this program, it is designed to take files
entered in standard input or from a text file -f flag>, and compare those files with the filenames in the current
data directory. If the names are NOT equal to eachother, the program
will delete the files else if they do equal eachother, the program
will ‘protect’ them and spare them from being deleted. So basically it
deletes all the files in the directory except those entered by the
user. The opposite of delete

After studying your _Toupper.b09_ and _Protect.b09_ programs, I
incorporated toupper into my program, as well as some of ‘protect’
and for the most part, after some fine tuning and debugging, things
started to work out. After giving the filenames of those I want
protected, in array form, the toupper procedure takes it and converts
all lowercase to uppercase and then list all those files to the
screen. Then the program opens up the dir file and
reads all the filenames into an array, and converts them to uppercase.
I then put in an ‘if/then/else’ statement that tests to see if
‘newname(count)’,the name array given by the user from keyboard, is
equal to ‘name’ which is the current filename being retrieved from
disk. If it is not equal it is supposed to print:

Deleting: filename

and if they are equal it is supposed to print:

Filename is protected

Now the screen will then print the filename from disk to screen
and it appears to work fine. The problem is, the program thinks that
all of the files are NOT-EQUAL, so if the delete command wasn’t
commented out, it would go one to delete all files in the directory.
It simply prints: ‘Deleting: filename’ for all the files, even tho the
files I entered were entered correctly were coverted to caps just like
the files that the program read from disk. I can’t for the life of me
figure out where the program is finding a difference between the two
sets of filenames. If you, or anyone else reading has a chance to go
over the code and maybe try running it from basic, I sure won’t object
. And keep in mind, I commentout OUT the ‘Delete Name’ command so
you won’t lose any files. I’ll include the source in the next message.

Thanks…

I’m afraid I may have tossed out a pretty bad curve with that last msg
regarding os9p3. It turns out that the one I have in memory has been stretched
by one byte at some time back about the kt boundary in an attempt to de-blob
the system, and has since propagated down thru all the boot disks I’ve made
since then. The real size of every copy of os9p3 (includeing from the
NITRO directories) is $140 (320 decinal) and the crc is $3B3304. It hasn’t
des that I know of. Sorry about the
confusion that $141 long os9p3 may have caused, its local to my system,
and not valid as an indicator of being nitro’d. Cheers Charley, Gene

In the file included from ancadv.c:11:

This same error also comes up in the libio.h file. What is it looking for?
I can comment these lines out and the program compiles fine but I am sure
that these lines are there for a reason and should not be commented out.
I downloaded the 2 files from here called:

gcc_258_cmds.lzh
gcc_2_5_8_lib.lzh

The other files seemed to pertain to GCC+. Do I need one or more of these
files also?

Also are there any little ‘tricks’ that one needs to know about using the GNU
C. It seems to give alot of warnings that CC never gives me.

I ftp’d over to chestnut a week or so back and picked up what looked like an
interesting file, as_h6309.zip. It purports to be an assembler for the
6809/6309 family of cpu’s, with the 6309 stuffs being switchable for ’809
only uses.
It ‘unzip’ed without errors leaving me with 2 doc/man files and a .exe file
that is not an os9 file. On inspection with dump, it has a string containing
the words PKLITE in the first sector. I’ve tried to further un-archive this
file to no avail. Am I going to have to carry it to a pc that has PKLITE on
it to unpack it any farther, or is there a so called PKLITE convertor
available for os9?

Frankly it doesn’t look too badly compressed, some of the other strings in
it almost survived!

Any help will be gratefully appreciated. Cheers all, Gene Heskett

Using the _ss_play call from the MM/1′s C-library, I notice that, on some,

lower speed than normal.

Does anyone know of any problems with the _ss_play command? Could it just be
that _ss_play can be affected by the CPU having a pretty heavy workload?
I doubt the latter, since I’ve never noticed such a phenomenon when running
any (with the exception of one) of the several digitzed sound players we have
available.

Anybody got any ideas?

If you have the ‘modpatch’ utility and a way to create one text file and
modify another (build) try this trick:

Create a text file on the disk with the following contents:

l dd
c 14 0 3
v
l d0
c 14 0 3
v

Call it “six_ms_patch” or something. Next add to the “startup” file on each
disk the line:

modpatch
This will link to the default drive (/dd) and drive zero (/d0) in memory,
modify the value at offset $14 to a 6 ms step rate and then update the
descriptor. This change is only to the descriptor in memory and will not
affect your disk.

This way you don’t have to go thru the process of creating a new boot disk
for each of the applications. If you can find someone who has a complete
OS9 level II system then you might ask them to set this up for you.

There are more ‘elegant’ solutions but this one works and is easy for a
beginner to set up. I know this because I used it myself until I figured
out the mysteries of ‘os9gen’ and ‘cobbler’.

I think you mean “Home Publisher.”

Anyway–what you have to do to get your drives to step at 6 ms is
modify the device descriptor modules for the floppy drives to indicate
that they can step at 6 ms. However, judging by your message (and by
“The CoCo Chronicles”), I would guess that you don’t run OS-9 as such,
but just put the Carmen Sandiego disks in the drives and type “DOS,”
so you probably don’t have the tools needed to easily find the bytes
to modify.

So, what you’ll need to find is someone with a CoCo and OS-9 who can
use ded or some other tool to modify the bootfile (which contains
the device descriptors) for you, or who can look on their copy of
those programs and tell you the offsets that you could perhaps modify
yourself, if you have a Disk BASIC program that will modify the raw
bytes on a disk and can handle OS-9 formatted floppies. (You’ll have
to modify four bytes in each descriptor: one to change the step rate
and three for the module CRC.)

Alas, I can’t help you, but I’m sure someone here will be able to.

Opinions herein are those of their respective authors and not necessarily
those of any organization.

a friend, who would recieve them and de-encode them, (we have been
working on graphics over the modem for awhile, we even have a terminal
program on the PC that is almost finished that will interpret OS-9 Level 2
controls so that a PC can run a good portion of OS-9 programs as a terminal)
but I just thought I would mess around with the routine since I took the
time to write it)

But all this cant be done unless I can examine the pixel at x/y to
send over..(after header info for palettes are set up) anyway, thanks for
any help in advance..

1.42 of g++ at uwisc and version 2.5.6 of gcc. Has any version of g++ 2.?.?
been ported to OSK? Has any version of gcc/g++ been ported with really working
-g (generate usefull debug info for MicroWare’s SrcDbg) or has gdb of some

If any of the above exists, where?

C’s stack

C’s stack
From: WDTV5 To: ALL

I would like to know if others have found a similar effect to the one
I just found while working on yet another edition of pf.

The effect in question is that the compiler apparently does NOT add
the stack requirements to the data size value in the module header!
At least not for arrays declared inside the opening { of a module,
which should put the declared array on the stack. It does ask for the
correct amount via a call to stkcheck, but its instant whole system
crash to exec the stkcheck code if the request is much larger than the
datasize currently defined in the modules header. As in 3x the
available memory in this case. And the instant whole system crash has
to be in the stkcheck code as the next statement was a debugging
printf call to show where the array was numerically. It never got to
the printf statement, ever!

I kept changing the array size, but found that it had no effect on the
actual datasize in the module header when changed from (27)(16) to
(134)(16)! Moving the declaration to a point above the function
declaration apparently fixed it just fine. From what I know about the
compiler, that puts the data area back on a pointer from the y
register. And no crash….

Is this the reason we’ve had to nearly always declare extra memory on
the CC invoke line via the “-m=xk” for all these years?

pf TNG
From: WDTV5 To: ALL

I’m making some progress in the re-write of printform to handle the
escP2 EPSON stuffs. The general outline is to make the config
file go up from 432 bytes to 2048 by allowing the use of any
character that will get past the “isprint()” function, minus of
course the ones already defined in the current version. That
leaves a few holes in the array that can be used for the escP2
specialty stuff.

I have in mind 2 methods of doing it. Method 1 will be an absolute
size command achieved via an added ‘.’ command. This would tend
to limit it to whole lines.

Method 2 will if the escP2 implementation allows it, cause a 1 step
up or one step down in size. This incremental method will be
integrated into the line position tally being kept such that we
can still do the proper line wraps etc. This method could be
expanded to allow absolute sizes too, but I need to see the
manual pages for a printer that does do “escP2″ things before I
tackle such a project in ernest.

This is going to need a basic list of char widths obtained from
your manuals under the “proportional” heading. They’ll be
entered into the file you feed to print_mod, and I’ll have to
assume they are in the printers basic “dot” width values. And
I’ll have to figgur out how to integrate that LONG list into the
config file, or attach it to the end thereby expanding it beyond
the 2k mark by about 114 bytes.

Why am I telling you’all this? Easy, I need somebody to mail me the
down and dingy details of how this works since my printer
doesn’t. Can somebody drop me an envelope full of a copy of
those pages from a manual? Don’t send the real manual, just copy
those pages.

Check with whomever you bought OS9 from. I think Microware has a tiered
pricing structure for Ultra C. I got my copy of 1.0 for ~$300 from PT via
Delmar. List price is something much more than that.

If you already have Ultra C then the upgrade is about $50 without the new
manuals. There are some difference between the original manuals and the new
ones but I don’t know if they’re worth it because I don’t know what the new
manuals cost.

There is an error the values I posted for dhrystones as compiled with Ultra
C. The command line I gave will cause the two modules to be linked as
I-code and the optimizing pass to made over the resultant file. I was using
a makefile that linked the files as .r files which means that the values I
reported did not have the advantage of the global optimization .

The correct values should be:

Header for: dry21
Module size: $1B0C #6924

Microseconds for one run through Dhrystone: 439.1
Dhrystones per Second: 2277.6

RE:a was thinking, file formats would be a problem..
and the CPU time could very well be a sticky point as well, although, I am
more worried about the file formats. A) Finding a file format that fits
those specs is probably gonna be difficult. and then B), even if you
find a file format, the average file of that format cant be all that
large, CoCoers arent used to real big files..now, if this were for UNIX
the file could be in upwards of 500k, and no one would think twice…if
the output was nice enough. As for translating gray scale from VEFs an
external program could be used to translate color VEFs to gray scale files
that pf could use (assuming a new format must be created), and while printing
in color would be nice..that could be
oopps, that could be “phase two”. I mean, I bet there are more users with
b/w printers than color. (I myself have an HP DeskJet 500, and a 500c)
Although the 500c isnt working right now..if you want a copy of my
DeskJet manuals, I will photocopy them off to you..(beca re

pf question

85908 25-FEB 23:59 Programmers Den
pf question
From: WDTV5 To: ALL

First to JRUPPLE:
While it might be nice for gui trained users, putting in a menuing
interface is not IMHO conducive to getting the job done in a timely
manner. There may be some who could pick the command line opts out with
a mouse quicker than I can type them, but the time to declare and show
the menu would be added too. Uh, maybe. Naahh..

As far as the fonts and the escp2 stuffs go, I suspect that could be
worked in with some additional monkey business to calculate the present
vertical lines per inch and keep a running total of it. I’d need to
fnboth the ^up and the ^down triggers.

However, thats not presently very handy due to the current usage of the
top row in that data array. So maybe we add 4 more rows at the
bottom. Or even (and I’ve given this some thought but it sure would
screw up the printing of already made files you’ve had for years) take
out the automatic toupper(c) and make the array about 2.4x bigger. Use
the uppercase to do, and the lowercase to undo, and start the basic
array at $30, restricting the access by the ^ triggers to just the
upper/lower alpha, but have the rest of those blanks filled in for ‘pf’
used config data, humm, I like that.

Heck, if we used the 0-9 area for a direct ‘use this size’ command, the
preparation phase of the editing would be a bunch simpler. However if we
start the triggers below ’0′, then print_mod is gonna require major
surgery. Making the array larger isn’t what I’d call major tho. How
many actual sizes are there in the escp2 command set?trcan handle 16 or more
intensities per color. I don’t have one of them puppies tho.

2. The formats individual line length in bytes. Thats an integer(16 bit)
Why? Well, here a full line in 24 pin could be an 8640 byte line buffer!

3. The formats total height in ‘load up a line and print it’ lines.
Another integer I suspect. So thats a 5 byte header.

Here I’d like to force the issue a bit and require “printer ready”
graphics, eg, a file which is, if arranged on paper according to those 4
items, a direct bit image of what you want to print. Or a negative image
of same. I don’t want to have to attempt to translate the color info in
a VEF or GIF into something that would look ok on paper. Unless of
course we’re talking color ribbons here. My one attempt at that was for
an amiga generated image at the tv station, we wanted to show the client
what his graphic would look like in print so we played around for
several days, using every option we coul ar regardless of how we twiddled
the drivers options. Not satisfactory at all and we never did show the
client anything but video. So the next question is obviously, other
than FIT, is there an existing gfx format that matches those specs, or
do we have to re-invent a new 4 cornered wheel here. FIT would be nice,
but to reduce one of those to printable would take more cpu time and
memory (and probably a smarter programmer too!) than we’ve got I’m afraid.
Go see your local astronomer for the real details on FIT. Its the
original, and presumably still the best “scalable” image transfer format
today. Bulky files tho I’m told.

It boils down to ‘which existing, commonly used file format would match
those requirements?’ Item 1 I’m sure will be the sticking point.

I’m not too allergic to attempting to wrap text around it either, but I
really don’t want to get into the centering and/or cropping of images,
so they need to be trimmed and cropped for this traly by a program that can
translate the bit image into the correct line buffers worth of process
red (magenta), process cyan, process yellow plus black information in
the proper order to be very simply read from the file and shoved out the
door to the printer. With the plethora of methods used, that translator
I suspect is going to be pretty specific to the individual printer.
“Process”, that sounds like an ink pushers lingo, is, I’ve done some.
In printing color to the paper, we’re starting out in nearly all cases
with white paper. The colors of ink used are “subtractive” in that what
almost looks like red ink isn’t, its magenta because it reflects both
red and blue light. If you want real red on the paper, you must also
overprint the magenta with yellow which reflects red and green but not
blue thereby absorbing the blue that the magenta ink reflected. To get
green, use cyan (no red) and yellow (no blue) which leaves green. Etc.

I’ve had my own colorhh use organic dyes. I used to formulate my own paper
developer too because the ready made stuff spoiled too fast, you could
see the difference from one 8×10 print to the next! I’m in the process
of clearing out a corner of the basement and planning walls for another
darkroom right now. I made the sink last summer. Anybody got a Bessler
23/dichro they want to sell? Make me an offer.

I suspect I’ll need copies of your printers manual to pull this bit of
magic off. BUT, Do not, repeat do not send me your original manual, I
found out the hard way they are the closest to being made out of
“unobtainium” as you could imagine. If you lose the one that comes with
the printer, it will take at least $100 in phone calls to the
vendor/maker to get a new one, probably 2 years later.

Gee, I wrote all that?

This is awful long for the forum, sorry.

Educate me here folks! Cheers, Gene (WDTV5@delphi.com)
