How to break out of WHILE ?

When I have a simple while loop, how can I break out of it? (e.g. break in C/C++).

    You break out of while when the conditions on top are not met

    Hi pavpav, 

    Thanks I thought so but will hoping RAPID supported a C-ish `break`.  But if that's not possible I'll add it to the while condition.

    The closest I can think of is the RETURN statement that will exit the current routine. That might work if you put your WHILE statement in a dedicated routine.

    Hey Pollux,

    You can also use the GOTO statement like this:

    MODULE WhileLoop
        VAR num count := 0;
        
        PROC TestWhileloop()

            WHILE TRUE DO
                
                IF count > 5 THEN
                    GOTO nextPart;
                ENDIF
                Incr count;
            ENDWHILE
            nextPart:
            TPWrite "Out of while loop";
            Stop;
        ENDPROC
        
    ENDMODULE

    hope it helps,

    But then this would do the same with less code and without the use of GOTO which I ware thought never to use when I started programming ABB robots.


    MODULE WhileLoop
        VAR num count := 0;
        
        PROC TestWhileloop()

            WHILE count <= 5 DO
                Incr count;
            ENDWHILE

            TPWrite "Out of while loop";
            Stop;
        ENDPROC
        
    ENDMODULE

    Best regards
