9.2.3 Phase 2 - Sorts

All of the work files are sorted in order to prepare for the
next processing phases.  Except for the Base Catalog
Structure work file (WORK.VCABCS) the files are sorted by
SYSID, ENDTS, VOLSER and DSNAME.  The BCS file contains
records for each VSAM cluster and data component type (DATA,
INDEX or SSET).  Consequently, the elements containing these
items (DAACNAME and DAAVCOMP respectively), are included in
the sort sequence.

In all cases, the NODUP option for PROC SORT is used to purge
duplicate data that may have inadvertently been combined in
the input job stream.
