Not necessary. You can examine the DSCB in the DCB exit, which 
has the additional advantage that you can examine ALL DSCBs in 
that exit for ALL of the data sets in a concatenation. This is
very much simpler than chasing SWA blocks to find all of the
DSNAMEs and then doing an OBTAIN for each.  Way, way simpler.
