'''EXIT''' is a DCL command that terminates processing of a command procedure or subroutine and returns control to the calling command level-either an invoking [[Command Procedure|command procedure]] or interactive [[DCL]]. The EXIT command also terminates an image normally after a user enters Ctrl/Y (executing another image has the same effect).

=Syntax=
<nowiki>
EXIT [status-code]
</nowiki>

==Status Code==
Defines a numeric value for the reserved global symbol [[$STATUS]]. You can specify the status-code parameter as an integer or an expression equivalent to an integer value. The value can be tested by the next outer command level. The low-order 3 bits of the value determine the value of the global symbol [[$SEVERITY]].

If you specify a status code, DCL interprets the code as a condition code. Note that even numeric values produce warning, error, and fatal error messages, and that odd numeric values produce either no message or a success or informational message.

If you do not specify a status code, the current value of [[$STATUS]] is saved. When control returns to the outer command level, [[$STATUS]] contains the status of the most recently executed command or program.

=Examples=
<nowiki>
$ EXIT 1
</nowiki>
The EXIT command in this example exits to the next higher command level, giving [[$STATUS]] and [[$SEVERITY]] a value of 1.

<nowiki>
$ CREATE E.COM
$ IF P1 .EQS. "" THEN INQUIRE P1 "Code"
$ CODE = %X'P1'
$ EXIT CODE
$
$ @E 1C
%SYSTEM-F-EXQUOTA, exceeded quota
</nowiki>

When the procedure exits, the value of $STATUS is %X1C, which equates to the EXQUOTA message. Note that you can also use the [[F$MESSAGE()]] lexical function to determine the message that corresponds to a status code.
