Re: A82: 2 questions (LINK & chars)



1. If you look in 82-ROM.TXT you should find the addrs for some of the
build in link rutines. Using them it should be a lot easier to make two
calcs communicate. The rutines i found on the ti82 for handling this are
very much like the ones on the ti85, so if you can find info/code from the
ti85, it should not be hard to use. The only problem is that no one have
check out the addrs for these adrsse in other rom versions than 19, so you
might have to include all of them in your program.

2. If you look at the code for the functions which displays text it is
pretty easy to find the data you want. The ram does not include a pointer
to the currect font, so you can not just change the font.
