RE: How to sort a flat text file on the 400.

[qsrvbas@xxxxxxxxxxxx (Tom Liotta)]

Tim:

Since I have no good idea how you'd sort a CSV file on UNIX, I'm not sure what 
you can do on the iSeries to make it any easier. The short example you supplied 
doesn't make clear whether fields in every line have the same width. You also 
don't describe whether you want to sort entire lines or just specific columns. 
You have apparently MM/DD/YYYY dates, but maybe you're only sorting by the 
first field.

If the columns aren't fixed-width, I'd probably just pass them all in to the 
QLGSORT API (and possibly QLGSORTIO) as lines in the input buffer and pull the 
lines from the output buffer before formatting specifically for any printing or 
other output and be done with it.

If they are fixed-width, you could still call QLGSORT against a flat physical 
file rather than a spooled file or even use FMTDTA. You do understand that you 
can override STDOUT to a physical file -- no apparent need for a spooled file?
