RE: Questionable practice in file handling in CL

I don't see a reason to do that now. It sounds to me like a S/36 throw-back.

Subject: Questionable practice in file handling in CL

I'm looking at a CL that:

1. deletes the 6 logicals on a single physical file
2. deletes the physical file
3. recreates the physical from the DDS
4. runs an RPG program that writes (20k to 30k) records to the physical
5. recreates the 6 logicals

The only explanation I can come up with is that it once was thought that the system would be faster if the logicals were built one at a time after the physical was built rather than during the running of the RPG program.

Does anybody have stats to back this up.

I think it's not needed and that a CLRPFM on the physical is all that would be necessary and allow each logical to remain during the run of the RPG build program.
