Re: Modernising the AS/400

Can't say enough good things about "Code Complete" except that it is Steve
McConnell, not Bruce.  It's published by Microsoft Press (you have to wonder
why they never read it) and carried by most of the computer book clubs.
It's the bible of modular programming and I agree, should be required
reading for any programmer.  It doesn't have a word in it about RPG, just
concepts.

On JAVA, I have a feeling it will be a great success on the 400, eventually
as performance improves, but a failure in the rest of the world and we will
once again have our own little language that no one else uses.

RPG IV, on the other hand, has become almost just like C, so if the AS400
does goes away, you can always fall back on C, on any platform, and it won't
be so terribly unfamiliar.
