Re: What bugs you about KLISTs in RPG IV?

Bruce,

This is exactly what we do.  Only the routine is in a /COPY member.

There are a couple more lines than in your example.   Like we set a return code 
so the
caller does not rely on an indicator.

I made mention to SAA in regard to different thread, but back in 1987 when it 
was
introduced we adopted a couple of it's concepts such as function isolation.  
This
pretty much forced us into heavy /COPY usage.  Well forced is a strong word.  
We chose
that over cut/paste 'cause we're lazy.

It has provided great benefits when a major overhaul has to be performed.

If the CHAIN operation code changes, we have a single /COPY member per file to 
change
then compile away.

Now that we are moving towards ILE, we are still sitting on the fence as to 
whether
this should be in a service program or not.
Regardless of how we exercise record retrieval, the request would stay isolated 
in the
/COPY.  It could just as well contain a CALLP instead of a CHAIN.

Any thoughts on using a service program for disk operations?
