Re: Reasons for using RPGIV

I doubt any argument is going to make a difference. Just another RPG
programmer terrified of change.

The reasons to use RPG IV would run for pages. Readability, maintainability,
That anyone would want to continue to write programs with 6 characters
variables, fixed format, global variable declaration still boggles my mind.
Not only the hell of writing them but maintaining them.

If I understand her correctly, her argument is that as a JDE shop that we
should NOT be using RPGIV at all, and that we should be writing /all/ code
in RPG/400. I don't necessarily disagree, in the case of simple mods to an
existing JDE program, but I would argue that /all/ new development should
be
done in free-form RPGIV.

Background:
We currently have a mixture of OPM and RPGIV code.

Some of the RPGIV is programs that have simply been run through CVTRPGSRC
to
convert them to fixed-form ILE source, other RPGIV code includes several
including entire sub-systems which have been written entirely in free-form
RPGIV utilizing service programs and binding source.

Other than hitting the RPG/400 compiler limits on the number of arrays,
tables, and files (which necessitates converting the program to RPGIV in
order for it to compile successfully), she wants me to present five
compelling reasons to justify the use of RPGIV, particularly free-form
RPGIV
code.

Any thoughts? I need ammunition!
