Tim, the wheel that you seek is already invented and spinning! The OS/390 SAS-brains at the SAS Institute have written a _GREAT_ routine that processes VTOC information--a process that can be lightly complicated when you consider all of the various DSCB types. You can find the code that you seek in the following library/member:

SAS.SAMPLE(MAPDISK)

If you are in an organization that has Berry Merrill's _AWESOME_ OS/390 performance management product, MXG, you can find a batch job set up to do this. Look at:

MXG.SOURCLIB(JCLDASD)

The JCL in the member, above, executes a couple of assembler routines that (you must pre-assemble/link and that) come with MXG. They are in the same Source library.

A final consideration may arise if you are in a shop which runs CA-MICS. CA-MICS has an optional DASD component that is called... that is called... that is... rats!--I was a MICS administrator for 6 years... but that was 7 years ago. Hey, if you guys _DO_ have CA-MICS then you will probably want to check with your MICS Administrator. Perhaps he/she is already collecting the data. (And the good news is that the data is stored in SAS data sets).

Oh, and another "final" consideration is the product Fast Dump Restore (FDR). We used to dump VTOCs via an FDR reporting program. I do not remember the exact FDR program, but your friendly DASD Administrator will undoubtedly be familiar with it.

Tim, best of luck in getting the ball rolling!

I hope that this suggestion proves helpful now, and in the future!
