Re: start 5250 session from RPG. CL, REXX, whatever...

I do not know anywhere near enough about Booths situation to give an
opinion one way or the other. I do know that several years ago a company
contracted with me to automate a process that was interactive only. They
did not have the source for the application, there were no APIs available
to bypass the interactive application processing, and they were, at awkward
times in the day/night/week, having to get management (well, authorized
personnel anyway) to sign on to the system and run through a few screens
selecting this and that, removing items, and the like which was a basic
pain for productivity.

At their request I wrote a RPG program (no Java, no webfacing, no
communications at all other than to the application) to simply drive that
application as if the program was an authorized user. The program did have
access to various tables to control what it did in terms of "filling out
various application panels" in a script like fashion. Using virtual
terminal APIs did mean getting to know 5250 data streams (at least to the
extent of how the application presented and received data), but it didn't
take that long to accomplish (OK, and I had worked with 5250 data streams
in the distant past). Whether this approach might be practical here, I
don't know. It could be if what the users currently need to "do" is fairly
well understood, the data they provide is currently available (or can be
made available) to the program, and there aren't a ton of errors in the
data causing the users to really make interactive decisions...

If you can pop a java window, you can pop TN5250J with a macro file that
can be dynamically generated and takes the user to the Yes/No prompt.

The steps before opening a 5250 session are not on 5250. They are on a
web page.

From my perspective, the only thing that opens 5250 sessions is a 5250
emulator (a program that handles 5250 data streams).
