I agree that nesting looping can be quite effective. I think the
biggest I've had was 5 loops going at once. However, I'm thinking more
along the lines of having things that could come up more than once,
but not necessarily at a given time or in any given order. Hmm.. I
don't think this is coming across right. If you use Repeat, While,
For...whatever...you MUST stay within those loops. If you have a
Repeat nested in another Repeat, then the bigger repeat WILL happen
when the smaller, nested repeat becomes false.
The other thing that I was thinking of, was jumping out of a For( loop
like the ways that were discussed earlier. If you put a Goto inside of
a For( loop and then include an End at the site of the label - that
won't work! For example;
:For(X,1,10
:If X=A
:Goto 1
:End
:Lbl 1
:If X=A
:End
When the calc runs across the End, it will automatically return to the
top of the For loop! Makes a mess, doens't it?
