RE: Adding parameters to procedures

David,

The issue I have is that you're throwing away some of RPG IV's nicest features:
the parameter options
of CONST, VALUE, OMIT and NOPASS.

If you add a parameter, and recompile everything, then you should really test
everything too.

On the other hand, if you add a parameter as NOPASS, you don't have to
recompile anything and only
have to make sure that the procedure functions as expected with and without the
parm.

You could get fancy with the DS parms and pass a value that lets you determine
what "version" of the
DS is in use, basically like IBM does with its APIs.

If you got a lot of info going in or a lot coming out, a DS might make sense.
But as an doing it that
way for every procedure? I don't think so.


Just my .02

Charles

Subject: Adding parameters to procedures

Hi,

We are looking at the possibility of standardizing our
procedures in the manner described at the link below.

The aim is to avoid touching any procedures that don't use a
parameter that has been added to an exported procedure. We
just recompile everything.

Each procedure uses a DS for entry and another for output
parameters. If a new parameter has to be added it is just
added to the DS in question.

I have a problem with this : it gives rise to horribly long
parameter names ( I've simplified in the example) and
debugging is annoying.
But my biggest concern is what else are we missing? Someone
out there MUST have already tried this system.

Any comments would be greatly appreciated.
