   Revised  :
   11-Feb-1992, RLB
      Packets for DAS versions <= 2.46.
   28-Oct-1992, RLB
      Packets for DAS version 2.47, EH implemented, ET has major
      changes, minor changes to other structures.
      Restructured, nested structures are arrays and/or unions.
      Fields marked <reserved in 2.47> are no longer defined in
      version 2.47 but are retained for backward compatability.
      FD is not defined in 2.47 but as it does not conflict with
      other structures, it is retained.
   23-Apr-1993, RLB
      Conforms with version 2.50 DAS code.  Added DR, updated EH and
      added compressed data to DT.  Also added disk and tape format
      block typedefs.
   22-Sep-1993, RLB
      Changes all types to stdtypes.
    6-Nov-1996, RLB
      Updated to 120 format, dropped FD and other obsolete fields
