EndWhile
(s) continuation-condition an expression to be evaluated.
(s) series of statements statements to be executed repeatedly until the condition following the While keyword evaluates to @FALSE.
The While statement causes a series of statements to be repeatedly executed until the continuation-condition evaluates to zero or @FALSE. The test of the continuation-condition takes place before each execution of the loop. A While loop executes zero or more times, depending on the continuation-condition.
The following statements affect continued execution:
Break Terminates the While structure and transfers control to the statement following the next matching EndWhile.
Continue Returns to the While statement and re-evaluates the expression.
EndWhile Returns to the While statement and re-evaluates the expression.
Note: EndWhile and "End While" may be used interchangeably.
