OK, its this entire thing I'm unsure about, and this is why I bitch about
TI releasing some more example programs. What I THINK I'm doing, is try to
find the starting memory address of the matrix, and put it in DE.

Huh? :)...What I thought I was doing was incrementing the memory address of
the matrix to get to the elements.

Yeah...I think so. I want the first row, first column...

This puts the acc into op1.

This puts OP1 to a matrix at DE in row/col bc.
So, what am I doing wrong?

To Pat:
I hope you didn't write those documents, because I've been laying into them
recently. If you did, I apologize...I understand that you did put work
into them, but being such an advanced programmer yourself, I think you
assumed too much.
The documents that WERE helpful were the ones with those small code
fragments that explained stuff...the recalling system variables, the
contrast changer etc., etc. It'd be great if you could merely add a small
example program to the bottom of each document that shows how to use the
documented ROM Calls.
Thanks.
James.
