I have spent countless hours investigating SMF records. As you do not have SAS and MXG (or equvivalent), I would start with the DAF program from CBTTAPE.ORG file 094.
SMF types 14 and 15 are the simpler ones to deal with, and you can use SORT for those, but DAF is way easier to work with. If you do go with SORT then I suggest that you search the web for samples and look at the User Guide on the IBM SORT web site. Or use sort to convert the dataset to a VB which you can process with a REXX program. If you have z/OS 2.1 REXX can read VBS directly.
