Meaning of L-O-I in HP3000 COBOL II DBGET 2

[Dan01]

I've seen L-O-I in other people's code, but do not know what it means:

CALL "DBGET" USING DB-MHS-BASE
DS-CASE-MANAGEMENT-SET
DB-MODE-6
DB-STATUS
L-O-I
DI-MHCASEMG-BUFFER
DB-MODE-6.

Would anyone care to give a guess, or know the answer? Thanks, Dan.

A quick check of "DBGET" syntax reveals that that is shorthand for "List Of Items".

Thanks Dimandja. This was bugging me! Dan.

Just a point of clarification: DBGET is an HP e3000 intrinsic function (subroutine) that is part of MPE's IMAGE database management system. The fifth argument to the call is a list of data elements to be retrieved from the database dataset specified in the second argument. The data name used for this list is, of course, programmer defined, e.g. there's nothing special about "L-O-I".

There are a couple of "special" list values including "@;" which retrieves all items in the data set and "*;" which retrieves the same set of items as the last DBGET. FMI, see the IMAGE/3000 documentation on docs.hp.com.

Thanks Glenn. I've always wondered about that but couldn't find the explanation. Dan.
