R: OPNQRYF - Zero records

Good morning. In order to retrieve the number of record of a file you may
want to use:
 RTVMBRD  FILE(YourFile) MBR(YourMember or *FIRST) NBRCURRRCD(&RKNO) , where
&RKNO is DEC( 10 0)
As far as i know, you cannot retrieve the number of record selected by
OPNQRYF unless you do CPYFRMQRYF.
Sincerely

Domenico Finucci

Oggetto: OPNQRYF - Zero records

I am trying to test if the OPNQRYF file produced has no records from the
selection criteria.

I can do this by using the DSPFD to an OUTFILE and then using DCLF and RCVF
to read the 1st record which will contain the &field MBNRCD , to inform me
if there are indeed 0 records.

But,

is this the best way to go ,

as this will only allow 1 file comparison in the CL program.

If I want to test any more files for zero records , then they have to have
their own CL programs.Which is obviously not ideal.
Also the testing of this is messy , as another file has to be created which
holds the testing files data.
