Here is a subroutine that uses no rom calles (great for 64k programs or OS-9).
The random number from 0 to 255 is returned in the A register, no other
registers are changed.
And here it is…..
RANDOM PSHS B
RND FDB 0
SEED FCB 0
Well, there you have it. I will be uploading it into the Asm Lag Database with
full documentation in the next few days.
Use any number (besides $FFFF) to reseed the sequence (it’s length is about
32,000 numbers long).
