Using QMF

Using messages with the REXX EXIT instruction

You can use the REXX EXIT instruction to exit a procedure with logic. QMF always issues a message when it finishes running a procedure with logic. If you use the EXIT instruction, the message you see depends on these factors:

Table 11 shows which message you see based on the given conditions.

Table 11. Messages returned from QMF commands in procedures

Nonzero return code from the last QMF command Procedure return code Message at completion of procedure
No 0 OK, your procedure was run.
No nonzero The return code from your procedure was 8.
Yes 0 The error message provided by QMF.
Yes nonzero The error message provided by QMF.

An error message takes precedence over the return code message if you have an incorrect QMF command and a nonzero return code.

If you want to show the error message from the last command and exit with a nonzero return code, use the MESSAGE command as in Figure 157.

Figure 157. Specify MESSAGE to see the error message from the last command.


"MESSAGE (TEXT='"dsq_message_text"'"
exit rc

The variable dsq_message_text is a QMF-provided REXX variable. You can use the MESSAGE command and the dsq_message_text variable to store and display a message after further processing has occurred, as shown in Figure 158.

Figure 158. The MESSAGE command displays the original error message.


 /* Monthly report                                           */
   Signal on error
   "DISPLAY TABLE JUNE_INFO"
   "PRINT REPORT"
   Exit(0);
 Error:
   Original_msg = dsq_message_text    /* Saves error message. */
   "RUN PROC GENERAL_RECOVERY"        /* This proc generates  */
                                      /* new dsq_message_text. */
   "MESSAGE (TEXT='" Original_msg "'" /* Display original error msg. */
   Exit(8);
