Re: Regarding retrieving source from modules

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

Hmm.. Okay, that makes perfect sense.  You can't optimize I/O
routines very much at all, that that's mostly what RPG turns out to
be.

Okay, I think I'll look at what I have to do to get PDM to set the
DBGVIEW to *ALL.

And, no, I do not plan on making that a part of my backup strategy,
just something to help me to be able to retrieve the source code and
to debug programs (I hate having to recompile each program twice
when I want to debug it, once with DBGVIEW *ALL and then again
with DBGVIEW *STMT [the default] once I'm done debugging).

Regards,

Jim Langston
