Re: OVRDBF from an RPG?

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.
