re: reading a big file

[boothm@xxxxxxxxxxxxxxxxx]

I'm not used to big machines and big files.  The box has V3R2 and I think
may be an ?F60? (its bigger than their development box, which they keep
referring to as a 45).  

The file I am concerned with has 5 million records.  I want to go through
this file making selections based upon choices made for several fields. 
Normally I would use the RPG cycle and bang down through the file (no K),
making the selection tests with the most limiting choice first, and as
soon as a record fails, goto end of cycle.  Any record that tumbled
through that series of tests would be written to a workfile, with a key
field made up with the sort-choices as made on the selection screen. Over
90% of the time the final work file will hold less that 10,000 records.

I've done this a lot on smaller files and smaller machines.  It offers a
real easy front-end for the user and is flexible.  

But I have never done this on a 5 million record file.  Am I about to make
a fool of myself? --
