Re: OS version for RDI -- WDSCI-L

Technically, given RPG III's monolithic nature, you can only really test the whole program; and unless
your changes involved only new variables, you really shouldn't just exercise the portion you (think
you) changed.

CVTRPGSRC doesn't change RPG III to ILE RPG, all it really does is convert RPG III to RPG IV
compatible syntax. Basically, just changing the spacing on the code.

Aside from a couple of op-codes that don't work, which you'd get error messages about, CVTRPGSRC is as
close to full proof as you can get.

There really is no good reason not to use CVTRPGSRC to get rid of the need form the OPM compilers.

For me, I have no problem to do that, but.. I'm only a member of our
team. Not everybody comfortable to write ILE RPG. It takes time.
Another concern is that writing a new program should be OK as we have to
testing the whole program. However, changing the existing big RPG program
is an issue. I believe the CVTRPGSRC should be working but I cannot just
make this assumption. If I convert the OPM RPG to ILE RPG, I still have
to test it (not just the part I make change). Due to the limited
resources, I will consider that "don't fix it if it is working", unless we
get the approval from our business user (project owner). To convince the
business user is totally another skill set..... Sorry, I may be too
careful.

Mark,

That's a great point! I guess it depends on which set of compilers the
CVTRPGSRC command comes with. Does anybody know?

Hello, all:

No one else has mentioned this yet, so here goes ...

Why not just license the ILE compilers, and any time you need to "touch"

an old OPM RPG/400 program, just use the CVTRPGSRC command to convert it

to RPG IV first, then compile it with CRTBNDRPG, with ACTGRP(*DFTACTGRP)

... (aka. "OPM compatibility mode")... This way, your shop should be
able to migrate everything to ILE smoothly, while saving money by not
needing to license the OPM compilers at all.

Does this not "make sense" and if not, why not?

Thanks,

Mark S. Waterbury
