repeat while

repeat while trueOrFalse

   statements

end repeat

The statements in a repeat while structure repeat as long as the condition following the word while is true. HyperCard checks the condition before the first and any subsequent iterations of the loop.

If HyperCard executes an exit repeat statement in the loop, it continues running the handler starting from the first statement after end repeat.

If HyperCard executes a next repeat statement, it returns immediately to the beginning of the repeat loop.
