Re: ILE questions: activation groups, rpg-cgi, classic web server. -- RPG400-L

Richard,

If you use the default activation group, static binding and binding directories 
are not
supported.  This also means CALLB and CALLP aren't supported, nor are
procedures (which are statically bound, hence unsupported by dftactgrp(*yes)).

If you're doing a conversion, DFTACTGRP(*YES) lets you make your RPGIV
programs act like RPGIII programs, which means you can use CVTRPGSRC and
easily "upgrade" (if that's the right word) to RPGIV.

When using static binding, then you'll have to specify a named activiation 
group, or
*NEW.  You can also use *CALLER to use the caller's activation group, but if the
caller's activation group is the default activation group, static binding, 
callp, callb, etc.
won't work.

What you use depends on what you want to do, or perhaps what functions you need
support for...

I think RPGIV presents a lot of very powerful options, particularly with 
prototyping
and binding, that we can take advantage of, but that requires using named or
temporary new activation groups.

I don't think I'm knowledgeable enough yet to comment intelligently about the
advantages of *NEW as opposed to QILE or a named group, but a lot of very smart
people watch this list....maybe somebody will weigh in?
