Compare PDSs for Members

Hi,

Suppose there are two PDSs (say 'A' and 'B') each with a huge number of
members.

A and B are expected to have some members with identical names. I need
to figure out which members of A are not present in B and which members
are common to both.

Obviously, manual check of the two PDSs would be cumbersome,
considering a big number of members.

Is there some way (REXX, batch FILE-AID etc) which can help me extract
the member list to a PS file..? Then I can compare the two files and
resolve my problem..?

Thanks..

I believe that File-Aid would do the job for you.

Another choice might be the ISPF option for invoking Super-C. As best I
can recall, Super-C would give you a report saying things like
(This is entirely inaccurate with respect to the actual wording)
PDS A has 3072 members.
PDS B has 2945 members.
There are 305 members in PDS A not contained in PDS B.
There are 178 members in PDS B not contained in PDS A.
There are 2767 members common to both libraries.
Then, it would get into how many of those commonly named members match
each other, etc.

Obviously, you could also create member lists of the two libraries, and
write a program to do a two file match, and produce a similar report at
the member name level. But then, you'd have to use something like
IEBPTPCH to print out the contents of every member of each PDS, and
write a program to do the comparisons of the member data where the names
match.

Almost certainly, Super-C would do that better than you could without
your spending 1000 hours on the program.

Have you looked at the IEBCOMPR Utility?

SuperC will do this easily.

Thanks Colin, Skippy and Joe....Your pointers helped a lot.....

SuperCE worked for now....
