      FUNCTION   :
             This block contains the Parameter Block used
             by the hardware crypto support and the necessary
             information to use it with the correct opcode and
             to find the corresponding key object.
      LOCATED BY : HCPKYMGO
      CREATED BY : HCPKYMCW
      DELETED BY : HCPKYMRW
      SERIALIZED :
             May only be used by one thread at a time.
             If necessary, a new working key should be obtained
             from the key object.
             It's within the responsibility of the user to
             control the serialization.
      RELOCATION CONSIDERATIONS : None
