Answer / prabhas

1. Using DCLF command
2. OVRDBF with Position parameter
DCLF FILE(&FILENAME)

OVRDBF FILE(&FILENAME) POSITION(*KEY 1 FMT2 X'123F')

The system searches for a record from the record format
FMT2.
A single key field is used in the search (even though the
key value may have more key fields).
The record contains the hexadecimal value 123F (the
hexadecimal equivalent of packed decimal value 123.0). You
get this record when it is found.

Answer / svankipu

See
1. In DCLF command u can declare a keyed-PF or an LF(having
desired keys)

2. In OVRDBF command u have an attribute called KEYFLD,
wherein u can mention the key-field of the above file.

Then you can use POSDBF command to position the PF or LF &
read it using RCVF command.
That's it!

can i use unique key in LF
