The best place in memory for short machine-language programs is page 3
($300.$3CF)

>>>>>>>>>>>>>>>>> FLAME ON <<<<<<<<<<<<<<<<<<<<<<<<<<<

APPLICATIONS (SYSTEM PROGRAMS) SHOULD NOT USE THIS SPACE!!!!!!  WITHOUT THIS
SPACE THERE IS NOWEHERE TO PUT SMALL ADDITIONS TO THE PRODOS MLI!!!  such as
device drivers, clock drivers, and print spoolers.  I have a very nice clock
routine for my hardware clock-less IIc using the VBL interrupts.  Much of
the time I can't use it because of system programs that overwrite page 3.
If they didn't, I could use it all the time, and make a print spooler that
would continue under other system programs than the one that set it in
motion.
