Description
The EXIT instruction is used to terminate repeat instructions
(FOR, WHILE, REPEAT) before the end condition has been met.
If the EXIT instruction is within a nested repetition, the innermost loop (in
which EXIT is situated) is left. Next, the first
instruction following the loop end (END_FOR, END_WHILE or END_REPEAT) is executed.
Example EXIT
If FLAG has the value 0, SUM will be 15 following the execution of the instructions.
If FLAG has the value 1, SUM will be 6 following
the execution of the instructions.
SUM := 0 ;
FOR I := 1 TO 3 DO
FOR J := 1 TO 2 DO
IF FLAG=1 THEN EXIT ;
END_IF ;
SUM := SUM + J ;
END_FOR ;
SUM := SUM + I ;
END_FOR ;
