Visual Age RPG can create Java classes from RPG source, I think. Booth Martin, on this list, might have more to say on that. The RPG can be imported from the iSeries to VARPG. I wonder whether this can be useful in converting.

Moving to an all-Java from heavy RPG? I hope not. Performance will probably take a serious dive. (Personal opinion - I think Java performance is pretty poor, generally, although IBM claims it is very good natively on the iSeries.)

You might also go to www.iseries.ibm.com/infocenter and pick North America, then V5R3 (or whatever the version of iSeries you have). Then look under Programming in the menu, then Java, then there is a topic on using it with other languages.

Good luck
Vern

Thanks a lot Charles. That solves my 'Hello World' problem, I surmise.:-). Well, this is the situation...I am a Java programmer and there ours is a pure AS400 shops where lots of programs are written in RPG and we are moving towards Java and we will be going through a translation project in a year or so and in the mean time I need to understand RPG so that when those programs get converted into Java I need to understand the Logic behind those RPG programs so as to make sure that no garbage is coming out into Java classes. Well, please let me know if that gives you any idea of the problem I am in...if not I will be glad to elaborate. Thanks a bunch for the response.
Mike.

That's it.  The whole program just 2 or 4 lines.  Now you know <grin>
Seriously though, I'm not sure Visual Age RPG is what you should be looking
at to learn RPG.  Visual Age RPG is for writing PC client programs.
Basically, it provides an easy way to write Client-Server programs in shops
that don't know anything but RPG.  I don't know what the differences are
between VARPG and RPG on the server.  But usually, when dealing with RPG you
are talking RPG on the server.
Now as far as learning.  The IBM manuals are here:
http://publib.boulder.ibm.com/iseries/v5r2/ic2924/info/rzahgrpgcode.htm
Additionally, you might want to look at the books available on one of these
sites:
http://www.midrange.com/
http://www.iseriesnetwork.com/
http://www.mcpressonline.com/
You might want to join the RPG mailing list also.  Since WDSc is simply the
editor.
