exception. You cannot receive a diagnostic message (if one were sent in addition
to the escape message) in the error-code data structure. You can use the message
handling APIs to receive messages from your program message queue and to
access the other messages that may be issued from the API. Appendix A of the
System API Reference
book contains an example of a diagnostic report program
that uses the message handling APIs.
When you instruct the API to return all errors in the error-code data structure, the
escape message does not appear in the job log. The escape message not
appearing in the job log is one of the major differences between letting the API
return errors in an error-code data structure and letting the API send escape mes-
sages. For the error-code data structure, the escape messages have been
removed from the job log by the API. If a diagnostic message is sent first, the
diagnostic message exists in the job log and can be received.
Accessing the HOLD Attribute—OPM RPG Example
The following is the RPG code used to access the HOLD attribute. This is the
same type of program as the RPG program examples in “Retrieving the Hold
Parameter (Exception Message)—OPM RPG Example” on page 3-6 and
“Retrieving the Hold Parameter (Error Code Structure)—OPM RPG Example” on
page 3-11. The program, named JOBDAPI, prints the value of HOLD if it is found
(17 on page 3-19). If an error occurs, the program prints a line that contains the
error message ID to a spooled file called QPRINT (18 on page 3-19).
