Steve:

Two possibilities come to mind at first:

Look at the Retrieve Display File Description (QDFRTVFD) API. I haven't gone 
through that entire API, but you ought to be able to interpret your record 
buffer by using the results of the API. No trivial effort there. Sure seems 
best to have this all wrapped up in a procedure or three.

Also look at the Retrieve Program Variable (QTERTVPV) API for OPM, or the whole 
set of debugger APIs for ILE (someone else will have to provide focused 
details). While this API requires some environment manipulation (debug) and 
compiled programs that keep variable names, it can work. I haven't done this 
from within the same program, but it might be worth a try.

IOW, I don't think there's much choice within RPG itself. But then again, if 
you write the program, you can make it do pretty much anything.
