Short question is: does anyone know what might cause a program to crash at the RETURN command?

I just rem'd out a block of code in a subroutine, and now the command seems to be causing a "Fields has stopped working..."-type crash. I used a plugin to make a message box pop up just before the RETURN command, and a different box directly after the subroutine. Only the first box appears before the crash.

Windows offered to debug it with Visual Studio, but the VS debugger proceeded to crash as well

There's most probably a mismatched call and or return.

I'm not 100% certain what you mean, but I'm not doing anything more complicated with subroutines than calling them from my main loop. None of them so much as call another subroutine, they just run and then jump back. Could you elaborate?

Did you rem from before the subroutine name, until after the return statement?
Did you remember to rem out all the calling gosub commands?
Can we have some sample code to work from?

I probably overreacted when I posted this, I managed to solve the problem by commenting out segments of the subroutine one at a time. The program stopped crashing after I commented out this debug code:

+ Code Snippet

`DEBUG
for c=1 to array count(Paths(0))
    text 10,c*10+200,str$(Paths(c).X)+","+str$(Paths(c).Y)
next c
for c=1 to array count(Sims(0))
    text 300,Sims(c).Path_Start*10+200,str$(c)
    text 320,Sims(c).Path_End*10+200,"/"+str$(c)
next c

It turns out one of the bits I'd removed was the declaration of the Paths array, though why this caused a crash at the return command instead of a handy "Array does not exist at line xxx" error is beyond me.

EDIT: Thanks for your help anyway Mobiius, and Kevin
