I'm curious as to WHY you don't use sub programs? I've just recently
started to, and I think it seems to work quite well, especially if you
use something quite often. Actually for two reasons; 1) it can save
space if the routine is repeated quite often, and 2) it can speed the
program up, again it seems to have more effect if the sub program is
used often. How do you work around an area in your code that has to be
used by more than one place? For example;
If A=10
Goto 1
......
If X=50
Goto 1
......
Lbl 1
.....
(at this point how do you get back to where you came from? I think you
have to add more labels after each "Goto 1", just to get back.)
If you used a sub program for label 1 it would save some space.
I agree that Repeat seems to be the fastest. I think it is just a
little bit faster than While. I'm not sure though, is Repeat faster
than For(?
When you use repeat to quickly get out of a Repeat loop, how do you
account for the "End"? Or do you use Goto to jump to just in front of
the End, but still within the loop?
Don't take any of this the wrong way. I'm not trying to beat a dead
horse, I'm just trying to come up with the best (if there is a best)
way to program these calculators. It's always fun to come across
something that I didn't know before, something that will help optimize
my stuff.
