I've been developing over the past few weeks a shell for the
TI-82 that contains some basic math functions (i.e. quadratic formula,
completing the square, other algebra/calculus material)...
My structure for the shell is complete except for the
functions themselves which need to prompt the user for real numbers (must be
able to input negatives and decimals), store them in a variable [mem address],
and use them for mathematical calculations (i'm pretty sure I'll be using the
OP* registers). How can I prompt the user for these numbers, echo that input
(would setting bit 3 of (IY+08) help?), and store these numbers in usable form
in memory?
Thanks in advance,
