Re: EGL for RPG programmers ?

In any case, if you are using EGL you are going to have to interface to RPG
on the back end. I cannot imagine anyone not having to do that and a lot of
shops are going to end up using EGL in the front end and RPG in the back end
so this discussion is very relavant to RPG.

The one thing that I absolutely suggest is that you create an abstraction
layer between the EGL or Java and the AS/400 RPG programs. Using Data Queues
or making program calls directly passing parameters is not a workable
solution. You want a solution where the EGL knows nothing of the RPG and the
RPG knows nothing of the EGL. You are simply sending message back and forth.


My opinion only.

Dear Mr Gibbs
Respectfully........disagree completely. Many RPG shops are looking to
replace RPG. EGL may be the replacement. I would like to know the
direction that other RPG shops choose to pursue.

Taking this conversation to the EGL list would be wrong. EGL developers
aren't concerned with issues faced by RPG developers. And replacing RPG is
the most pressing issue for many RPG shops.

Thank you

I do realize this is the RPG forum, but pursuing EGL from an RPG shops
perspective is a relative topic I believe.

Actually, it's not relevant. This list is (theoretically) for discussion
of RPG programming, not evaluations of other languages.

Discussion of how RPG programs respond to EGL invocations is relevant here.

Technical discussion of EGL would be appropriate in the EGL-i list (
http://lists.midrange.com/listinfo/egl-i).

Discussion of pursuing EGL would be appropriate in the EGL list or the
MIDRANGE-NONTECH list (http://lists.midrange.com/listinfo/midrange-nontech
).
