Very few RPG programmers could do this, Buck.  Perhaps you'd like to publish
your tools open source to help some other folks?

And completely changes again for WAS5.  Which is my point.  You are
completely at the mercy of whatever the WAS team decides next.  And then
read Paul Nicolay's post on trying to redeploy existing applications.

<laughing>  Yeah, a teeny-weeny WebFacing application.  In any event, Buck,
you actually prove my point.  You wrote CL commands to MOV objects around.
Me, my product generates stuff directly into the IFS.  It worked great with
WebSphere 3.5, but not with WAS4/Tomcat.  I changed it to work with
WAS4/Tomcat, and it didn't handle WAS5.  This idea of write once, run
anywhere is being completely trashed by the folks who think they should be
able to dictate our naming conventions.  Heck, I can'y even upgrade to V5R2
unless I rewrite my web applications.

This is not a good concept.  It's as simple as that.
