Viewing a Different Module

To change the module object that is shown on the Display Module Source display, use option 5 (Display module source) on the Work with Module List display. You access the Work with Module List display from the Display Module Source display by pressing F14 (Work with Module List).

If you use this option with an ILE program object, the entry module with a root source, COPY, or listing view is shown (if it exists). Otherwise, the first module object bound to the program object with debug data is shown. If you use this option with an OPM program object, then the source or listing view is shown (if available).

An alternate method of viewing a different module object is to use the DISPLAY debug command. On the debug command line, type: 
DISPLAY MODULE module-name

The module object module-name is shown. The module object must exist in a program object that has been added to the debug session.

For example, to change from the module DBGEX in Figure 1 to the module cproc using the Display module source option, follow these steps:
  1. To work with modules type DSPMODSRC, and press Enter. The Display Module Source display is shown.
  2. Press F14 (Work with module list) to show the Work with Module List display. Figure 1 shows a sample display.
  3. To select cproc, type 5 (Display module source) next to it and press Enter. Since a root source view is available, it is shown, as in Figure 2. If a root source was not available, the first module object bound to the program object with debug data is shown.
