70's hardware.. IBM put the M36 environment on certain models after the V3r2
RISC conversion so this is mid 90's? - I forget the models.
I'm aware of several of those still running (but I don't work on them).

Subject: Re: RPG36 with OCL examples desired; 1) insert-a-record 2)

The distant fog of my brain suggests to me that the "A" was for Add-only and
was seen as only moving the file's end-marker.
The "U"pdate allowed update, and add. There was no concept of an indexed
and keyed file at that time so there was no such thing as an insert. Why
would there be, since there was no random access.
(fwiw, it was mentioned that you can use AS400's RPG in the Sys36
environment. Its hard for me to believe that there is any 1970s hardware
still in use. Working with a more modern compiler would make any work in
that system a whole lot easier, plus give much better
performance.)
