Re: getting up to speed

Jon,

I have thought about the redbook, but it is such an old version that I'm
reluctant to recommend it. Among other things, I'm a fervent proponent of
/free and things like BIFs and such that I find it very difficult to go
back to old code (And I know about OLD code. I began programming in
RPGabout 1977).

While the code is not /Free (which wasn't available when the Redbook came out) it was all written in a style that can be directly converted. i.e. No MOVEs, GOTOs, etc. I can't guarantee that every line of every sample converts directly - but that was the intent. Most of the BIFs were around then - a few nice ones have been added but most were in play. I think you are doing people a disservice by not recommending it.

BTW, I seem to remember a surname of "Paris" in the author's roster list
:-) Don't you have the clout to get IBM bring out a new version of the
book? :-)

We did try - the result in the end were the two redpieces on APIs and Error Handling. There just isn't the funding for Redbooks in general that there once was. As Brian said there is new Modernization one on the way - but it doesn't have the same in-depth teaching approach that the Sorcerer's guide and redpieces did.

It would be nice to update the original - but I don't see it happening. It was a massive undertaking - probably 2 man years at least and that's not counting the time spent by IBM's editors.


Best Regards,

Luis

There's always the "good ole" RPG Redbook - pretty good place to start as
it has a bit of everything. Written for V4R2 (?) I think so a fair bit has
changed - but it was partly written to show RPGers how and why they should
make the switch to RPG IV. Everything in there from soup to nuts.

Joe.

Scott Klement has a nice intro to ILE in his website ( http://www.
scottklement.com ). It's a little bit dated, so if you check IBM's
Infocenter you can download the RPGLE reference manuals and check any
enhancements for the OS version you are running currently. Also, get a
copy
of the ILE RPG Programmer's Guide (Infocenter).

If you haven't done so already, I would strongly suggest you learn
SQLboth, as standalone apps (Procedures, functions, etc) and as
related to
RPG ("Embedded SQL"). Go the /free route (forget all that columnar stuff
:-) )

And, as I am sure you already know: Practice, practice!!

HTH,

Luis

I was a programmer quite some time ago, as a matter of fact I last
worked
on
RPG400. With the limited opportunities for admins, I'm looking to get
back
into programming. Can anyone suggest books or training that I can use to
get
back up to speed. I have not worked ILE at all.



Thanks,
