How do I compare two PDS on z/OS

I am migrating from one ADCD system to a newer version. I wanted to see the differences in the supplied members.

In ISPF 3.13 (SUPERCE) you can compare dataset members.

• Enter the New DS Name and the Old DS Name
• If you leave the PDS Member List blank, you get prompted on the next page to select the members of interest. I specified *
• Compare type 1 (file) gives you a report on the members which are the same or not. See Output from file compare
• Compare type 2 (line) shows the contents which are different.
  • Listing type 2 (Delta) gives just the changed lines. See here
  • Listing type 3 (CHNG) shows the change in context. See here
  • Listing type 4 (Long) shows the all the members

Output from Line compare, CHNG output(3)

This shows the changes in context.

• At the front of the line is I or D, to show what was added or deleted
• The TYPE MAT= is the count of matching lines, and the line numbers within the files.
• TYPE=RPL is the count of lines replace, and the line numbers within the files.

Output from Line compare, Delta output(2)

This just gives the inserted and deleted lines. It is a subset of the data above.
