repeat until

repeat until trueOrFalse
   statements
end repeat

The statements in a repeat until structure repeat as long as the condition following the word until is false. 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.
