Is there a way, in pure Basic, to do the equivalent of a call... execute subroutine code, without disrupting any For/While loops you are in?
The easiest and most correct way to call a subroutine in TI-BASIC is to simply use
prgmXXXX. If you're using Hybrid BASIC, you can copy an archived subprogram to a temporary program and call it.
Edit: An alternative would be to Goto out, then use a Goto at the end of the subroutine to jump back to a Lbl right after the Goto inside the loop, like this:
Code: :For(X,1,10
:Goto DX
:Lbl RX
:End
:Return
:
:Lbl DX
:Disp X
:Goto RX
Here's a screenshot of the program. Anyone who wants to beta test it, please private message me and I'll send it to you.
BUGS I KNOW OF: Dividing with a 1-term denominator gives a Domain error on the deltaList line.
Also, the program currently discards any remainders from division. If someone can advise me on how to use it, I'll try to.

Update!
• 2.0 RC1 – Division bug resolved. Error catching for divide by zero added. Trailing parenthesis removed where possible. Zeroes algorithm improved. Older version used the solve() built in command. This version uses a modified rational zeroes test ( x = p/q )
