RE: OVRDBF from an RPG?

Thanks all,

I was not thinking of using EXTFILE because of the fact that I'd need to call a function each time to get the library name in each module for each file. If there are other files in other procedures I would need to do the same. The OVRDBF, however, would take care of all the files. Although I still need to find them all, change them to USROPN and open and close them.

work with the UsrOpn and ExtFile keywords for your file
definitions. And you also can use QCMDEXEC with UsrOpn keyword.

Subject: OVRDBF from an RPG?


Hi,

I've another problem with files with the same names in
different libraries.

I have a Procedure1 in Module1 that calls Procedure2 in
Module2. Procedure2 opens implicitly a file F2. Then it calls
Procedure3 in Module3 which opens a file F3. It's possible
that other procedures are called, opening files in this same,
cascading manner.

So after my first call to Procedure2, I'll have Files2 and 3
open when control returns to Procedure1.

On my next call to Procedure2, I may want Files2 and 3 of a
different library.

Could I just open and close my files in the beginning of
Procedures2 and 3, and issue an OVRDBF in Procedure1 ?
Would it work? Would I have to use QCMDEXC or is there an
easy API way?


Thanks.
