You may want to reconsider your logic. If not, you could create a "breakout" variable that would get set in the deepest loop (just before quit) and propagate upward until you get back to the top. Again, this is a band-aid solution, and I think you might reconsider your program architecture and the use of nested repeats.

Use quit to break out of inner loop. And quit again to break out of the outer loop.

Ditto on Jon's advice. Generally if you want to be able to exit from an inner loop to one several levels higher, you need to plan for it and generally add exit condition variables. Sometimes it helps to encapsulate each repeat level in a procedure (method).

PRI overallMethod ' level 0
REPEAT '1
  level1Method

PRI level1Method ' level 1
  REPEAT '2
    CASE expression
      0: 'stuff
      1: if level2Method
            return

PRI level2Method ' level 2
  REPEAT '3
    CASE expression
      0: 'stuff
      1: return true ' indicates that level 1 should exit
  return false ' indicates normal exit.  level 1 should repeat

in fact subconsciously·, ·need for a "goto" instruction blocked my mind, (assembly habits ...)

·thank you all . exit condition variables fixed the problem·
