Hi Jon,
It's a lot easier to use the VTOC Command Processor (CBT File 112) than
to do what you're describing.

Is it possible to compare two SYSRES volume dataset and generate indirect

If you use VTOCLIST, realize it might have duplicate DSN's for multiple extents.
ISPEXEC LMDxxx returns REXX compatible list of datasets on a volume or dsn
prefix similar to ISPF 3.4. You could LISTDSI or LISTDS for each dataset to
find the uncataloged datasets.
Alternatively, you could use ISPEXEC LMDxxx for old sysres and create stem
variables for the datasets (e.g. DSN.dataset-name) and LMDxxx for the new
volume that checks if the stem variable exists.
Another possibility, you could use ISPF 3.4 (sort if necessary), save the list
for both volumes, edit the new sysres list, set bounds for the DSN, compare to
old sysress and keep only new lines.
If ISPF 3.4 supports == line command, then you could create an exec that
catalogs an uncataloged dataset. specify the exec name on the first dataset, ==
on the second and == on the last.
