RE: Calculating the number of records parameter for batch extract

I think it's 64K in v4, but I could be wrong.  4K is the system default, and
I believe 32K was the max for CISC machines.  I'd be interested in your
results, I've gone with the system default and calculated my own blocking. I
don't remember getting a huge performance boost although I enjoyed copying
the ovrdbf code from program to program.
