Tony,
It is quite easy to split the group of records into multiple members.
Here
is a sample JCL which will give you the desired results of splitting the
first 999 groups of records into a PDSE each containing the group of
records. I also assumed your Input is already sorted on the field you
want
to split. I assumed that the split field is 44 bytes in length. If it is
different then you can change it in ALL the places referred by KEYBEGIN.
This job creates a dynamic JCL which will then be submitted via INTRDR.
Take a look at the output from Step0200 and then if everything looks ok
then change the statement
//SORTOUT DD SYSOUT=* to //SORTOUT DD SYSOUT=(*,INTRDR),RECFM=FB
If you have more than 999 groups of records we will copy the rest of the
records into another file which will then be used as input file to
further
split. I will show you how to build the dynamic JCL's based on that. I
chose the split to be 999 groups as the maximum number of DD statements
per job step is 3273, based on the number of single DD statements allowed
for a TIOT (task input output table) control block size of 64K. This
limit
can be different depending on the installation defined TIOT size. The
IBM-supplied default TIOT size is 32K.

I have a dataset that contains records with a field, by which I need to
create a separate dataset that would contain all occurrences of that
field. For example the file, FB100, looks like
value1 other data.....
value1 other data.....
value1 other data.....
value2 other data.....
value2 other data.....
value2 other data.....
value3 other data.....
value3 other data.....
value3 other data.....
value4 other data.....
value4 other data.....
value4 other data.....
My final product must be a series of datasets:
hlq.value1.records
hlq.value2.records
hlq.value3.records
hlq.value4.records
There may be hundreds/thousands of possible values, hence
hundreds/thousands of datasets. I have accomplished this in 3 phases,
first pass reads the data, uses ICETOOL OCCUR to list the values, second
phase reads the OUTPUT and formats DD statements and OUTFIL OUTREC
statements, the third phase reads the original data to create the
numerous
output files. I used a newly created PDSE as the output file whereupon
the third phase created several thousand members.
It works, after a fashion, but I'd like a more simple solution.
