I would not assume the search done by ISPF is the same as the search

You may need to know the details of each search algorithm to know if
they are equivalent.
Several potential problems with the suggested DFDSS approach:
DFDSS will only find datasets on primary volumes - any datasets
migrated to ML1 or ML2 will be ignored and not deleted.
Although the indicated job will not actually write any data to the
DUMMY output dataset, the DFDSS DUMP will still incur the overhead of
reading through all data of the datasets being deleted.
The TOL(ENQF) should become a problem (delete failure) when it is time
for the DELETE to occur if any other address space has the dataset enqueued.
If there are not that many datasets and migration is a possibility, I
would be tempted to look for some BATCH REXX approach with LISTC and
DEL, which would handle migrated datasets. If there were 5K+ datasets
involved, using the Catalog Search Interface to identify the datasets
rather than LISTC would take more work but would be considerably more
efficient.
