EXIT

Statement - Exit from a loop statement

Remarks

The EXIT statement indicates that the current loop (WHILE, REPEAT or FOR) must be finished. The execution continues after the END_WHILE, END_REPEAT or END_FOR keyword or the loop where the EXIT is. EXIT quits only one loop and cannot be used to exit at the same time several levels of nested loops.

• 
  

• loop instructions can lead to infinite loops that block the target cycle.
