Hi’ All

How to exit while loop and continue next command ?

Example

VAR num sum;

PROC testwhile()  
WHILE TRUE DO  
Incr sum;  
IF sum = 10 THEN  
TPWrite “Sum :” \Num:= sum;  
! ---------- Exit while loop and continue command  
ENDIF  
ENDWHILE  
ENDPROC

PROC summ()  
testwhile;  
TPWrite “Exit loop while”;  
ENDPROC

Thanks for help.

Hello  
There is no break command but you could set a condition for the while loop like WHILE NOT sum = 10 THEN

Something like this

VAR num sum;  
VAR bool bExit:=FALSE;

PROC testwhile()  
WHILE NOT bExit DO  
Incr sum;  
IF sum = 10 THEN  
TPWrite “Sum :” \Num:= sum;  
bExit:=TRUE;

! ---------- Exit while loop and continue command  
ENDIF  
ENDWHILE  
ENDPROC

PROC summ()  
testwhile;  
TPWrite “Exit loop while”;  
ENDPROC
