I got this portion of instructions from a similar discussion in the past.
Hope it helps in something:
How to retrieve the RPGLE source
It is possible to retrieve source from RPG programs if the program has
been compiled with the correct parameters. The following procedure will
retrieve the source from single-module RPGLE programs compiled with
CRTBNDRPG with DBGVIEW(*LIST).
The program could be modified to handle RPG III programs compiled with
OPTION(*LSTDBG) and multiple module ILE programs. As far as the experts
know, the retrieval works with the exception of list directives (i.e.
/EJECT) and color/highlight special characters.
