Adding/Removing Programs from a Debug Session
You can add more programs to, and remove programs from a debug session, after starting a debug session. You must have *CHANGE authority to a program to add it to or remove it from a debug session.
For ILE programs, you use option 1 (Add program) on the Work with Module List display of the DSPMODSRC command. To remove an ILE program or service program, use option 4 (Remove program) on the same display. When an ILE program or service program is removed, all breakpoints for that program are removed. There is no limit to the number of ILE programs or service programs that can be in or removed from a debug session at one time.
For OPM programs, you have two choices depending on the value specified for OPMSRC. If you specified OPMSRC(*YES), by using either STRDBG, the SET debug command, or CHGDBG, then you add or remove an OPM program using the Work With Module Display. (Note that there will not be a module name listed for an OPM program.) There is no limit to the number of OPM programs that can be included in a debug session when OPMSRC(*YES) is specified.
