Creating a Listing View

A listing view contains text similar to the text in the compiler listing that is produced by the ILE RPG compiler. The information contained in the listing view is dependent on whether OPTION(*SHOWCPY), OPTION(*EXPDDS), and OPTION(*SRCSTMT) are specified for either create command. OPTION(*SHOWCPY) includes /COPY members in the listing; OPTION(*EXPDDS) includes externally described files. OPTION(*SRCSTMT) allows the program object to be debugged using the Statement Numbers instead of the Line Numbers of the compiler listing.

Note:
Some information that is available in the compiler listing will not appear on the listing view. For example, if you specify indentation in the compiler listing (via the INDENT parameter), the indentation will not appear in the listing view. If you specify OPTION(*SHOWSKP) in the compiler listing, the skipped statements will not appear in the listing view.

You create a listing view to debug a module by using the *LIST or *ALL options on the DBGVIEW parameter for either the CRTRPGMOD or CRTBNDRPG commands when you create a module.

You can encrypt the listing view so that the listing information cannot be viewed during a debug session unless the person knows the encryption key. You specify the encryption key using the DBGENCKEY parameter of the CRTBNDRPG, CRTRPGMOD, or CRTSQLRPGI command. You specify the same key when debugging the program to view the text of the listing view.

The compiler creates the listing view while the module object (*MODULE) is being generated. The listing view is created by copying the text of the appropriate source members into the module object. There is no dependency on the source members upon which it is based, once the listing view is created.

For example, to create a listing view for a program TEST1 that contains expanded DDS type: 

CRTBNDRPG PGM(MYLIB/TEST1) SRCFILE(MYLIB/QRPGLESRC)
          SRCMBR(TEST1)  OUTPUT(*PRINT)
          TEXT('ILE RPG/400 program TEST1')
          OPTION(*EXPDDS) DBGVIEW(*LIST)

Specifying DBGVIEW(*LIST) for the DBGVIEW parameter and *EXPDDS for the OPTION parameter on either create command creates a listing view with expanded DDS for debugging the source for TEST1. Note that OUTPUT(*PRINT) and OPTION(*EXPDDS) are both default values.
