** Actually, I tried to send the file but it was bounced because it was
over 30,000 bytes. The file can be retrieved at the url below; its name
is ENGR2210.inc.
Bill,
This is clever; thanks! I have to think if it'll do what I'm really
looking for, though. It might, but I'm not sure. I am looking for a
way that the labels are generated automatically, and branches to them
can be calculated automatically, through macros. So I don't want to
"set" the adresses of the labels as you've done. This may be a minor
issue, but I can't tell yet.
I'm attaching ** the file that started all this for me: its Brad Minch's
file of "structured macros" that are used in the pic18f2455 for usb
purposes. The total code for that is available at:
http://pe.ece.olin.edu/ece/projects.html
(I am working with the Lab 2 for 18f2455 one)
But the reason I'm attaching the macro file is that I think it'll
clarify why I'm not sure this will work.
I'm actively looking into this now, so I may be able to report more
later. I appreciate your suggestions, but don't jeopardize your "day
job" to keep providing me with excellent help!
Ben
PS I am attaching the DOS version of this file, but can send a slightly
hacked-up linux version if you prefer.
