True, but one advantage to a "make" utility is that it could be set
up to also recompile the modules.  make will only recompile them if
the source has changed since the module was last compiled, so you'd
simply put commands in the Makefile that created all of the modules,
and it'd determine whether to rebuild them...

This really makes a big difference when you've got a lot of modules
that all need to be bound into a program.  Saves a lot of time
compiling stuff that didn't change :)

At any rate, John, I think you see my point.  Sure there are ways
to work around it, but I think the extra difficulting in maintaining
RPG IV is the reason that IT managers are hesitant about moving
from RPG III to RPG IV.  --NOT-- because of the differences of the
RPG w/CF Spec vs. RPG IV, vs RPG III.

Yes, I understand what they are, John.  However, what was the point
behind using different terminology?  No, this isn't a big huge deal,
but its irritated me for a long time :)
