      All releases of CP prior to ESA 2.0 use DDEVSCYL and
      DDEVECYL for minidisk extents.  In ESA 2.0, DDEVSEXT and
      DDEVEEXT were defined for minidisk extents.  These new
      fields were added for FBA because FBA minidisk extents are
      in blocks instead of cylinders and a block number could be
      larger than a halfword.  But the time will come when CKD
      dasd is so large that cylinder extents may grow larger
      than a halfword.
      Starting with ESA 2.0, DDEVSEXT and DDEVEEXT should always
      be used for both CKD and FBA minidisk extents.
      ESA 2.0 must still be able to process directories created
      with previous supported releases of DIRECTXA.  Because of
      this, directory processing modules must consider the
      possibility that the new fullword fields may not contain
      the minidisk extents.  If the DDEVFWEX flag in DDEVFLGC is
      not on, then the old halfword fields will contain the
      minidisk extents.  In this case, when HCPUDR gets a copy
      of the DDEV it will copy the contents of DDEVSCYL/DDEVECYL
      into DDEVSEXT/DDEVEEXT.  So, starting with ESA 2.0, the
      rest of CP only needs to use the newly defined fullword
      fields.
      Directories created with ESA 2.0 (and later releases of
      CP) must be in a format that is compatible with all
      previous supported releases of CP.  For this reason, CKD
      minidisk extents are still stored in the old halfword
      fields as well as the new fullword fields.
      When ESA 2.0 becomes the oldest supported release,
      DDEVSCYL and DDEVECYL will no longer need to be
      maintained.
