Re: Example using a boolean variable with a loop

Aye, that would work, but as I mentioned in the other post, something like this:


FOR x = 1 TO 50
            IF UCASE$(states$(x)) = UCASE$(state$) THEN
                            ok = 1
                            found = x
                            EXIT FOR
            END IF
NEXT x
IF ok = 1 THEN
            PRINT state$; " was found at index "; x
ELSE
            PRINT state$; " was not found"
END IF


could be also be written as something like this:


FOR x = 1 TO 50
            IF UCASE$(states$(x)) = UCASE$(state$) THEN
                            PRINT state$; " was found at index "; x
                            EXIT FOR
            END IF
NEXT x
IF x = 51 THEN
            PRINT state$; " was not found"
END IF


because x will be 51 if and only if EXIT FOR was not executed. The NEXT x increments x, then checks to see if x <= 50. When x is 50, NEXT x turns it to 51, then exits the loop. However, if a match had been found, EXIT FOR would exit the loop before x becomes 51.
