Reader Feedback and Insights: Group Job Limitation

June 14, 2002 Timothy Prickett Morgan

Hey, Ted:

I’m writing in response to the first tip that appears in the “Odds and Ends” column, May 17, 2002, Midrange Guru, OS/400 Edition.

I’ve always understood that when you transfer to a group job, the job that you leave doesn’t continue running, but it stops until you return to it. Am I correct? If so, you should tell your readers about this limitation.

— Fernando

Yes, Fernando. You are correct. Only one group job runs at a time.

String Parameters of Various Lengths, Take Three

June 14, 2002 Timothy Prickett Morgan

Hey, Ted:

The May 29 Midrange Guru, OS/400 Edition, article, “String Parameters of Various Lengths,” is a great explanation of the CEEDOD API, but I don’t see the point in using the technique in this context. A simple variable-length field used as the parameter is far more flexible and avoids the overhead of operational descriptors

and the extra API call. Use of the CONST keyword allows you to pass fields of different lengths and non-varying-length fields as parameters, and you can use the %LEN function in the subprocedure to find the length of the string field. Am I missing

Searching Message Text

June 14, 2002 Timothy Prickett Morgan

Hey, Ted:

Is there a way to print or query a message file?

My problem is that I know the message text and need to find the message ID.

— Bill

Use the Display Message Description (DSPMSGD) command to build a spool file:

DSPMSGD RANGE(*FIRST *LAST) MSGF(xxx) +
   DETAIL(*BASIC) OUTPUT(*PRINT)

Then display the spool file and search it.
