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.

Demo Script

  show bkgnd field "demo field"

  put return & "    Point at the number to stop counting..." ¬
