As input I have a dataset with a list of dataset
names from a catalog (really several catalogs),
in columns 1 thru 44. What I want to do is
include or exclude dataset names in the file
based on patterns like you might enter on ISPF 3.4
xxx.yyy.*.zzz.**
ttttt.*.rrrrrrr.**

Frank seems to be un-retired today, so maybe he will have some clever solution
with DFSORT.
But I do stuff like this all the time by simply FTP'ing the information down to
my PC, loading it into MS SQL, and then writing SQL queries to extract the
information I want. The SQL LIKE predicate can do a lot of the pattern
matching you seem to desire.
Another thing you can do with the data on your workstation is to use UNIX
regular expressions. RegEx has something of a learning curve, but it is very
powerful once you get the hang of it.
I also expect John M to chime in with all the wonderful things you can do using
z/OS Unix System Services. So you may not even need to leave the z/OS platform.
