Iteration Termination Operators
EXIT, Return and Continue Operators
EXIT operator placed in WHILE, REPEAT, and FOR loop body leads to immediate loop termination. Good programming practice appeals to avoid such a technique, though it's handy enough. Let's consider, for example, array element with defined meaning х.
 | The easiest way to organize linear iteration is to use FOR loop:

For nested loop, EXIT operator finishes only "its" loop, outer loop continues to run.
RETURN operator backs up from component immediately. It's the only way to terminate nested iterations without an additional check for conditions. Though you should not trespass on it because it's difficult to deal with the text of component having, e.g. 50 outputs.
CONTINUE operator leads to immediate moving to the next loop iteration omitting expressions next to CONTINUE.
