Assume that you want to process the records in FILEA arranged
by the value in the
Cust field with program PGMD. You can specify:
OVRDBF FILE(FILEA) SHARE(*YES)
OPNQRYF FILE(FILEA) KEYFLD(CUST)
CALL PGM(PGMD)
CLOF OPNID(FILEA)
DLTOVR FILE(FILEA)
Note: The
FORMAT parameter on the Open Query File (OPNQRYF) command is not needed because
PGMD is created by specifying FILEA as the processed file. FILEA can be an
arrival sequence or a keyed sequence file. If FILEA is keyed, its key field
can be the Cust field or a totally different field.
