It is not mandatory to use OVRDBF(*Yes) before OPNQRYF. You
can still use OPNQRYF without OVRDBF.
But here the pupose of the OPNQRYF won't be solved. Opnqryf
creates its own Open data path and to share the same data
path in a program we use ovrdbf share(*yes), if we do not
use ovrdbf, then program will have its own ODP, so it will
read the file from begining on which query has been run. So,
OPNQRYF selected records will have no importance. So, we
need to use CPYFRMQRYF command and put the selected records
in to runtime file and use that file to read in program

It also depend on how the PF was created initially. At the time of creation of PF,if SHARE parameter is specified as *YES, we do not need to specify OVRDBF Share(*yes).
By default it is *no when we create a PF.
