Until

Repeat ... Until <.expression.>

Parameters: NONE

Returns: NONE

A Repeat-Until loop executes its sequence of constituent statements continually, testing an expression at each Until statement. When the expression returns True, the Repeat-Until loop terminates.       The code inside a repeat until loop is always executed at least once, since the Comparisons expression is only evaluated when execution reaches the closing statement. Giving them the opposite functionality of While-EndWhile loop blocks. FACTS:       * Repeat-Until must be paired.       * The Repeat must preceed the Until statement. You'll get a syntax error otherwise.       * You can exit a Repeat-Until loop anytime with the Exit or ExitRepeat statements.       * Do-Loop Statements can also create Repeat-Until styled loops by placing the 'Until' Comparisons expression after the Loop statement. Mini Tutorial:       A simple Repeat-Until loop      Repeat    ; Draw a dot at a random position      Dot Rnd(100)+100, Rnd(100)+100    ; display the screen      Sync          ; this loop will be repeated until    ; the user presses the Space Key   Until SpaceKey()      Print "You pressed the Space Key"      WaitNoKey   Sync   WaitKey
