Maybe Vern is thinking of a program designed for use with a "SPECIAL" file (Device parameter value)?

Hi, Vern,
Happy New Year!
It is simply not possible to create a service program using any of the OPM languages or compilers, including RPG/400. Perhaps it was ILE RPG IV?
All the best,
Mark S. Waterbury

I found it interesting some years ago to look at the _R* functions - there are some functions there that just are not available in RPG - IBM just didn't choose to include them.
There was a community-offered generic tool to work with data in RPG - probably a service program. This was in RPG III, IIRC, and there were things it would not handle - like columns with null attributes, maybe. We used it when I worked at RJS Software.
So I looked at the _R* functions, and they could have handled all that the tool did not, so far as I could tell. Never did continue with it - would be interested, just for fun, to see it again, though.
Cheers
