[A83] Re: TI-OS IM2


If you want to run a larger program, you may consider some of the ideas
below....

If you made a small interrupt routine that called your program, that should
work. The only problem I can think of here is memory addressing. All the
addresses in your larger program would have to be relative (not using JP or
CALL <label>). Perhaps you could use a memory pointer table...put the
addresses of your labels into a table (use org 0), and add the address of
the start of the program to these labels to get the correct address. Another
option would be to have your interrupt routine run a basic program that
called an assembly program...I don't know how well this would work or if it
even would work, but it's an idea. Naturally, I don't think you would want
to runa  basic program at 120hz so you probably would need a counter so the
calc wouldn't slow to a crawl....

Hope these ideas help a little!

Can someone check why this program works on VTI and
not on a real TI-83:

Also, how do I disable APD? Where is the APD counter
stored?

How do I make a large program that runs in the TI-OS
as an interrupt? Smiley (program above) uses the APD
RAM which is not big enough.
I've tried using the interrupt to call a program, but
the calculator crashes, even when I save all the OPs
and registers.
Also, romcalls should work shouldn't they because they
don't change the shadow registers?
