EXIT

Purpose

Exits a processing loop created by a WHILE or ON command regardless of the outcome of the command condition.

The WHILE command is described later in this chapter.

Terminates WHILE and ON command processing.

Syntax

►►─── EXIT ──── . ────────────────────────────────────────────────────────────►◄

Usage

Considerations

EXIT can be used in conjunction with the REPEAT parameter in an ON command.
Control passes to the next command outside the WHILE or ON structure following an EXIT command.
EXIT is typically used following an IF statement that tests for a secondary condition.

Example

The statements below illustrate the use of an EXIT command. The DISPLAY command is executed when A is greater than B or when Z becomes greater than 100, whichever occurs first:

WHILE A LE B
  REPEAT.
    ADD 1 TO Z.
    IF Z GT 100
    THEN EXIT.
    ADD 1 TO A.
  END.
DISPLAY.
