Re: OPNQRYF multiple times in same program

One CL program can do multiple OPNQRYFs, however a CL program can only open
and read a file one time.  If the CL does the OPNQRYF which is then read by
an RPG/COBOL/whatever program, then this can happen multiple times.

When I have a need to have a CL do multiple OPNQRYFs for it's own behalf, I
simply call a sub program to do my bidding.  It's not as efficient as you
might like, but it works well.

CL is a wonderful language.  It's too bad that not enough IBMers are CL
literate.  If more were, maybe they would extend it, which is essential for
the future of the platform.

Hi All,

I have a batch program that is;
1. OVRDBF ... Share(*Yes)
2. Performing an OPNQRYF selection
3. Does the Call to a COBOL program which reads sequentially thru the file.
4. DLTOVR
5. Then the program goes to sleep for 4 hours and then repeats again from
step
1.

It has been some time ago that I programmed an OPNQRYF statement but my
memory
seems to remind me that I could have a problem reading the file the 2nd
time!

Am I correct in assuming this?
Is there an additional CL command I need to specify?

During the sleep period additional records will be added to the file
specified
in the OPNQRYF selection

Thanks
Dennis Nel
