Re: rpg debug issue

I am trying to debug an RPG program. While running and debugging the
program I am trying to display certain fields getting read into the
program from an externally defined input primary file. When I do an EVAL
to display some field values, they are blank or zeroes when I know they
should have values. Other fields contain correct values. What could
cause this to happen? I am not manipulating the fields in the program at
all.



The compiler does a default optimization where it doesn't bother to load
fields that aren't used in the program.

- Code H spec DEBUG(*INPUT) or DEBUG(*YES) if you are on V5R4.
- Code H spec DEBUG(*YES) if you are pre-V5R4.

There's a page in the debug section of the ILE RPG Programmer's Guide
called "Unexpected Results when Evaluating Variables":
