That's actually incorrect. Any token or command which requires the use of an End statement pushes another pointer onto the stack. While this includes the obvious While, Repeat, and For loops, it also includes Then. If you reference the page on memory-leaks it says:
Simply put, a memory leak is where you use a Goto/Lbl within a loop or If conditional (anything that has an End command) to jump out of that control structure before the End command is reached
It can be noted, however, that a single line If statement can usually be used with a Goto as it does not have a Then … End block.
Looking at the code that was provided:
//Shortened for my own clarity
If [A](A,B)=2:Then
L+1→L
Delvar SDelvar T
If L≥7:Goto 8
End
If the
Lbl 8 is on the same level of the stack as the
Goto 8, it will be fine. As it was described, to me it sounds like there
is a memory leak here but it really depends on where
exactly in the code the label is. For example…
This one would have a memory leak:
While 1
Lbl 8
prgmDRAWMAP
Repeat K
getKey
End
prgmDRAWMAP
If [A](A,B)=2:Then
L+1→L
Delvar SDelvar T
If L≥7:Goto 8
End
End
This one would not have a memory leak:
While 1
If 1: Then
Lbl 8
prgmDRAWMAP
End
Repeat K
getKey
End
prgmDRAWMAP
If [A](A,B)=2:Then
L+1→L
Delvar SDelvar T
If L≥7:Goto 8
End
End
