has anybody seen a single logical type 30 record which has been "split" into multiple physical type
30 records? Is such a logical record guaranteed to have its "segments" physically contiguous? Or
could a different SMF record be written in the middle of such a logical type 30? I'm trying to figure out how
to process such a thing short of loading the information into a database and extracting it later. I am also
worried that the "first segment" could be written to one MANx dataset and that record causes SMF to
switch to another MAN dataset. In our processing, this would result in the two segments being in different
sequential, GDG files. Because we do GDG-all processing to combine these GDGs daily, the segments could be
out-of-order in a physical sense. And separated by quite a number of other records.
Any words of wisdom? Is there some SORT that I could do which would guarantee that the
"split" type 30s would be in order after the sort?

John, when we processed SMF, the processing program(s) were such that
the order of the segments was not significant.
Our processing used a pair of CLISTS that did this:
1. List the cataloged GDG datasets.
2. Sort the contents of each dataset based on joblog information
3. Create SORTINxx DD statements for each of the datasets, along with
the other DD statements, etc. for a MERGE.
4. Submit the MERGE job, merging all the GDG members to tape.
Our job scheduler was set to trigger on completion of the MERGE job and
submit the remainder of our SMF processing.
We used a Automatic Command in JES2 to do a "I SMF" command on each
image at midnight; IEFU29 exit caught the switch and submitted
processing based on time-of-day (midnight to half-hour past midnight
dictated daily processing; any other time submitted just a basic SMF dump.)
If I can find any of this stuff, I'll share it with you offlist.
