E@DBKFNDEQ
Name
The E@DBKFNDEQ call has the following format:
DN@<Logical>(E@DBKFNDEQG)
where <Logical> identifies the database file and index to use to perform the E@DBFINDPRVRNG call.
Description
E@DBKFNDEQ inquires on the Index for the key fields that match the values you set in the record retrieval variables (D@ fields) corresponding to the index key fields. This call works as the E@DBFINDEQ (E@DBFINDEQ) call works, but E@DBKFNDEQ returns only the keys from the Index.
