Exiting For Next loops

[larrybtoys]

Question for you GB32 gurus out there. I understand that it is not good programming practice however can GB32 handle exiting a For Next loop with a GoTo?

Example:

For T% = 1 to 100
    If T% = 10
        Goto Skip_All_Loops
    Endif
Next T%
'
For Y% = 1 to 100

    If Y% = 20

        Goto Skip_All_Loops
    Endif

Next T%
'
Skip_All_Loops:


I know the proper way to do it buy I have a few older programs similar to this and would like to know if it will cause some sort of stack issues. TIA

Yes sure sure you can do!
As long as you Goto inside the procedure function or a sub.

And if you want to leave a Proc/Sub directly out of a Loop/or you can use Return.
If done this since 30 years and never got any issues..

Proc Abc()
 Dim a, b, x, y
 While a > b
   If x = y
   Return
   EndIf
 Wend
EndProc

As Roger Cabo says, it is possible and GB32 can usually handle it, but it is not clean code and may cause an issue (extremely unlikely).

A cleaner alternative would be use Exit For, which cleanly ends the loops, as in the following two examples:

Dim T%, Y%

For T% = 1 To 100
 If T% = 10
   Exit For
 EndIf
Next T%
'
If T% = 101
 For Y% = 1 To 100
   If Y% = 20
     Exit For
   EndIf
 Next Y%
EndIf
'
Skip_All_Loops:
Debug T%,Y%
Debug.Show

...or...

Dim T%, Y%

For T% = 1 To 100
 If T% = 10
   Exit For
 EndIf
Next T%
If T% = 10 GoTo Skip_All_Loops
'
For Y% = 1 To 100
 If Y% = 20
   Exit For
 EndIf
Next Y%
'
Skip_All_Loops:
Debug T%,Y%
Debug.Show

You can also use Exit Sub, Exit Proc, if you like to go out of the Proc/Sub directly.
