The ILE source is used to detect errors in and eliminate errors from program objects and service programs. Using debug commands with any ILE program that contains debug data you can:
Before you can use the source , you must select a debug view when you create a module object or program object using CRTRPGMOD or CRTBNDRPG. After starting the you can set breakpoints and then call the program.
When a program stops because of a breakpoint or a step command, the pertinent module object's view is shown on the display at the point where the program stopped. At this point you can perform other actions such as displaying or changing field values.
