Hi guddu............
OVRDBF is not mandatory before doing OPNQRYF. OVRDBF is
only used to share the open data path within the calling
program(i.e we can use the selected records from OPNQRYF in
further program whose call is being made after
OVRDBF+OPNQRYF).
But is we dont use the OVRDBF command then open data path
will not be shared and if we done the RCVF on that file
after OPNQRYF(WITHOUT OVRDBF) then the selected records
from OPNQRYF will not be used and this RCVF will process
all the records from that file.
OVRDBF command is used just to share the open data path (By
specifying SHARE(*YES).
We we want to use the selected records from the OPNQRYF in
our further programs which call after this CL then we can
use CPYFRMQRYF command to copy all the selected records
from this OPNQRYF and then RCVF on this new file(which has
got generated by CPYFRMQRYF).
