CPYFRMIMPF can use a LOT of DASD

[Vernon Hamberg <vhamberg@xxxxxxxxx>]

I'm trying to get TPC-H tables on our 400, for testing. Got the DBGEN
program converted enough to get flat files written in IFS. One of them is
over 6,000,000 records and should end up about 800meg in size, plus
indexes, if attached.

What I did was CPYFRMIMPF to get the data to a physical file. But, WOW! The
temp file (in QRECOVERY) was over 5gig, with record length = 990. I'm sure
there're good reasons for this, but oooooooooooh, could you run out of
space in a hurry. We were somewhere around 75% when I started and were
close to 95% during the copy.

It's done now, but I'd probably try to write a direct load to the physical
for later.
