Re: Fwd: OS/400 V4R5 and OPNQRYF

["James W. Kilgore" <eMail@xxxxxxxxxxxxxxxxxxx>]

Al,

AFAIK, OS/400 V5 data base enhancements are available for -new-
development and should not break any existing applications.

For example, when date data types were made available, you had to use
RPGIV to work with them.  RPGIII programs just issued a warning at
compile time and did not make the field available to your program.  But
that didn't mean that your RPGIII programs failed to work.

The way I read into the SQL only (no DDS equivalent) enhancements will
result in OPNQRYF not being able to -use- the new data types.  OPNQRYF
will be limited to whatever you can define with DDS.  To use the new
stuff you must use SQL.

If this interpretation is off base, then IMHO, you will see a whole
bunch of companies that decide to freeze their systems at V4Rx and milk
the system for all it's worth just as the CISC users (and there's a lot
of them) are content to stay at V3R2 because they use their AS/400 to do
back room accounting and have other platforms for their ewhatever.
