The error messages section lists error messages that can occur when you use the API.
These are message IDs that normally exist in the QCPFMSG file. You may want to program for these messages regardless of the high-level language that you are using. If you need more detail about the messages, use the Display Message Description (DSPMSGD) command.
For a listing of the error messages in Retrieve Job Description Information (QWDRJOBD) API, see Error messages.
