Hi, Peter,

Hmm... that might still work, if compiled with CRTS36PGM ...

I think it was in RPG II that when a file was specified as Output, and no
Add flag, the file was cleared before writing to it.  Assuming it was a
sequential file and not a direct load where you had to specify the rrn of
each record written.

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
Vern
