Hello,

Need know if this code is a problem for stack overflow?

_start:
If _counter >= 14 Then
Incr Temp
If Var1 <> 0 Then
Incr Var2
If Var3 <> 200 Then Goto _start 'jump out of a, if structure!!
End If
End If

Best regards

Hi,
I did'nt test it but this code will give a overflow for the variables because it seems to be a loop without exit
you dont make any control of the increasing

ex : if you use byte the var temp will go to 255 then 0 and so on

no that can not result in a stack overflow.

a problem is something like this:

main:
gosub abc

abc:
goto main
return
