Hi,

"OBTAIN <RECORD-NAME> DB-KEY IS DIRECT-DBKEY", will get the record instance for the record mentioned based on the db key.

What would "OBTAIN DB-KEY IS DIRECT-DBKEY" (no record name mentioned) fetch? I can see this being used in a program i am analyzing but cant make any sense out of it....

TIA!PAV

DB-KEY is unique for a record occurance. Record Name in this syntax is optional.
Hope that solves your question.

Each record occurrence is assigned a unique numeric identifier, called its database key (db-key).
A record occurrence?s db-key consists of a 32-bit field that typically contains a 23-bit page number and an 8-bit line number. The page number identifies the page in which the record occurrence is stored and the line number identifies the location of the record occurrence within that page.
IDMS/R uses database keys to keep track of where in the database record occurrences are physically stored.
