Re: A86: THE ROM FOR THE 86




you start from scratch, kinda.  You just take the code and rewrite it
into 86 asm.  For example (85 to 86 porting is faarily easy...) Say the
line in the 85 prgram is this:

ROMCALL _BUSYOFF

Then, u would change it to:

call _clrLCD

Get it?  Prting gets difficult when u get into 82 and 83, because each
set of calculator programmers have includes designed for their calc.  So,
you really have to know the different syntaxs to port well...if ur
interested in trying it I suggest start with an 85, as it is most closely
related to the 86.  You also run into porting problems such as addressing
and screen size.  Always lots of fun ;)  So, overall, programmers usually
just rewrite the program completely, but use the other calcs code as an
outline.
