RE: F SPEC to clear a file?

["Bob Cozzi" <cozzi@xxxxxxxxx>]

Buck,
I remember when I was writing "The Modern RPG (III) Language" back in
1988 that a file opened for Output and one opened for Output-ADD were
treated the same in RPG. I think the ADD is required if you want to use
the "ADD" identifier on the output specifications, but other than that
nothing happens to the file.

However, that was NOT the case in RPGII. When they moved from a "file"
system to a database system the meaning of Output and Output-ADD became
the same to RPGIII and then, of course, to RPG IV.

When Jon speaks, I look carefully before answering.  It was my
recollection that O in RPG/400 + did not clear the output file like it
did on S/3/32/34/36.  So I tested it:

fmastest   o    e             disk
C                   SETON                                        LR

This did not clear my file.  So I went hunting through The RPG
Reference, V5R1, but could not find a specific reference.  The S/36
manual wasn't very helpful either. Hm.
