user index (was: work files in qtemp)

[fkany@xxxxxxxxxxxxxxxxxx]

What's a user index?  Do you have examples of how to create and use a user
index?

Douglas,

Files, or any object for that matter, placed into QTEMP go away when the
job ends.  The QTEMP library is unique for each job and only exists while a
given job is running.

Probably the most common way to get objects into QTEMP is to use CRTDUPOBJ
although there are several others.

I would like to suggest the use of a user index for your purposes.  I
rarely use work files anymore having replaced them with user indexes.  They
can be created on the fly, the format is flexible, the data is sorted as it
is added much like a logical file, and they perform well.  According to IBM
documentation they are faster than data files.

HTH,

Rick

I have been working on a program that will reuqire me to use some sort of
temporary hold file, a friend suggested that I use a work file in qtemp for
the processing of the data...however, I have never used work files before,
let alone in qtemp.

Should I just create the file in my library and then copy it to the qtemp
directory and then process the data deleting the file once I am done? Any
other suggestions would be appreciated.
