Two Easy Ways to Debug CL Programs

CL
Typography
  • Smaller Small Medium Big Bigger
  • Default Helvetica Segoe Georgia Times

When I need to debug a CL program, I don't use the Start Debug (STRDBG) command. Instead, I enter the following command to force the commands in the program to be recorded in the job log.

CHGJOB LOGCLPGM(*YES)

After executing the program, I use the Display Job Log (DSPJOBLOG) command to check each command and parameter.

If this technique doesn't provide enough information, I insert the Dump CL Program (DMPCLPGM) command into the program. I recompile and run the program again; then I display the QPPGMDMP spooled file so that I can see all the variables used in the program.

Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
