I don't agree that it would be harder to maintain what was going on.  Yes,
someone might have to learn something new - is that so terrible?  But the
api's involved are some of the simplest.  And I knew people that couldn't
grasp the concept of a chain or a setll, they actually read every record
of the file looking for the one they wanted.  Would you think it
unreasonable for them to learn something new?  Neither do I.  The API's
are well documented.  And I often put comments in my code going straight
to the web site with the documentation on that API.  Granted, the way IBM
moves their web sites around can frustrate some of your links.

A straight RPG method, using API's would definitely blow the doors off the
CL method as far as performance goes.

And doing a DSPFD to either print outs or to an outfile are subject to the
whims of IBM and may change format with each new version of the OS.

Why use 2 files in a CL when you could do that in RPG?

Here's an example:
I have an application that retrieves the list of files in a library, and
then does some quick math to see if I need to reorganize the physical file
member.

I don't want to do all libraries on my system, but only certain ones.  So
I
put the list of libraries I want to reorganize into a physical file.

If I could open up more than one file in a CL it would be a simple CL
program.

Read from the list of libraries.
For each library DSPFD into a file, then read through the file and check
for
members to be reorganized.

As it is right now, I have to have 2 CLs.  One to read the list of
libraries, one to read the list of members.

In no way would I think this better written in RPG.  These are fairly
simple
CL commands, DSPFD, RGZPFM, etc.. that are being called that are very
easy,
quick, and explicit in CL.  In RPG I would have to set up system calls,
etc... and it would be much harder to maintain and understand what was
actually going on.  I'm simply trying to use the appropriate tool for the
job, in this case CL.
