Ok. The original poster (Kaare) never told us WHY he had
a "requirement" that the file be in memory before his program
would run (maybe he is trying to convince a recalcitrant
customer that the reason the program is slow is I/O), but if
Kaare's program has to run at 11:30 and it takes 5 minutes
to bring in the file, why not simply start the program at 11:25
instead? Maybe he thinks that it is faster to load the file in
one go rather than record by record. I  think the presumption is
that the "bring" can be done many pages at a time. Paul, any
light on this?
