A better green-screen debug method id described in Debugging RPG IV Programs - The Green-Screen Way. The article generally describes STRDBG. But at the end, it covers the use of Service Entry Points (SEPs) and how the debug batch jobs with them. I recommend learning this method and using it. -- Tom

Also, you won’t CALL the program. The SBMJOB command will call the program. — Tom

Please go back to your original question and note that STRDBG is step 3, and RLSJOB is step 4. — Tom

1. SBMJOB ... HOLD(*YES)
2. STRSRVJOB JOB(jobnbr/user/jobnam)
3. RLSJOB JOB(jobnbr/user/jobnam) When Start Serviced Job display appears, press F10
4. STRDBG When source is displayed, When source is displayed, set a breakpoint, press F12
5. Call the program.

Please let me know whether the above procedure correct or wrong? And, please correct me if I am wrong.

BTW, you can make STRSRVJOB a little easier by using the SBREAK debug command to set a service entry point. See the SBREAK help on a debug command line for basic details. — Tom

Please show the STRDBG command that you used. Did you exit the debug display with F12, and not F3? Also, did you set any breakpoints after the DSPMODSRC display opened?

The debugger that I use most is the System i5 Debugger. It’s okay once you give yourself some practice.

The next levels of the debugger are nicer, but might need more practice. WDSC or RDi both include debugging facilities. You can also examine debugging through iSeries Navigator-> Databases-> Run SQL scripts… Start the SQL window, and select Run-> Debugger. It’s intended for debugging your remote SQL requests, but it can be used however you see fit.

Hi Tom,

Please tell me about the modern debug function.

You didn’t say what the error message ID is, so I have to guess that it’s CPF1938. The STRDBG command doesn’t throw that message ID, so you probably tried to run a debug command before you released the job. Maybe you tried to set a breakpoint. You can’t do that until after you release the job. The only command you can run is STRDBG, then you must release or start the job, and then you can set a breakpoint or display a variable. Personally, I would use a more modern debug function rather than trying to use STRSRVJOB through a terminal interface. — Tom
