They are close enough that the differences don't matter unless you intend to
compile the source on a genuine System/38.

It sounds like you're stepping into an interesting situation.  Don't worry
too much about the RPG II stuff.  The reason it is still RPG II is because
it's probably working exactly the way they want it to, and don't intend any
major changes.  Ever. <grin>  Since there is already RPG IV code in the
shop, I suggest that you do all your new work in RPG IV.  If you have to
maintain an RPG III / 400 program, convert it (CVTRPGSRC) before doing the
work.  If you run up against specific problems, post the details and we'll
get them ironed out.  RPG books are available on http://www.midrange.com .
