There is also an LE version which does milliseconds for the delay interval. Check the manuals for the specifics.

William,

if you are positive that the data is in sequence already, then you can use

MERGE FIELDS=(.....)
SUM FIELDS=NONE

this way you can avoid the overhead of sorting the data again.

I suspect that you have an overflow condition where the SQLDA area at the end of working storage has been overlaid. I would analyze the dump to check for a storage overflow condition.

both do the job, it's a matter of your shop standards or if there is no standard, then your personal preference.

it's like asking which is better 6 donuts or a half dozen donuts

you could use dynamic allocation via BPXWDYN and create as many as you wish.

just remember that restart / recovery using pds members can be much more challenging than qsam files.
