     NAME       : PROP
     DESCRIPTION: PROP SUPPORT DSECTS AND COMMON BLOCKS
     DSECT      : PROPCOM
     FUNCTION   : PROP COMMUNICATION AREA; PROPCOM
                  DESCRIBES THE CONTENTS OF THE AREA DEFINED IN
                  DMSPOP TO ALLOW THE COMMUNICATION OF FLAGS AND
                  OTHER DATA BETWEEN THE MAIN PROP MODULE,
                  DMSPOP, AND THE ACTION ROUTINE MODULE, DMSPOR
     Notes - This COPY file contains DSECT's exclusive to
                 PROP support. The following DSECT is part of
                 the PROP programming interface:
                   PARMLIST - Parameter list passed by PROP to
                              a PROP action routine.
                 See the individual DSECT description for more
                 information.  The start and end of each
                 programming interface are marked by "GPI" and
                 "End GPI", respectively.
                 All other DSECT's are internal to PROP
                 processing.

                IN THE ROUTING TABLE.  SINCE IT IS POSSIBLE FOR
                THE KILL BIT (PCOMKILL) TO CHANGE WHILE THE RTABLE
                IS BEING LOADED, SPECIAL HANDLE WAS CODED INTO DMSPOL
                TO MAKE SURE THE NEW STATUS OF THE PCOMKILL FLAG IS
                PRESERVED WHEN THESE BITS ARE RESTORED.
                WHEN DEFINING A NEW BIT, CONSIDER WHETHER THE BIT CAN
                CHANGE WHILE A ROUTING TABLE IS BEING LOADED.  IF IT
                CAN, THE BIT SHOULD BE PLACED IN THE SECOND FLAG BYTE
                (PCOMFLG2), SINCE THE BITS IN PCOMFLG2 ARE NOT SAVED
                WHEN LOADING A NEW ROUTING TABLE.
                IF A BIT THAT CAN CHANGE WHILE LOADING A ROUTING TABLE
                MUST BE PUT IN PCOMFLAG, BE SURE TO CHANGE DMSPOL SO
                THAT THE NEW SETTING OF THE BIT IS PRESERVED WHEN THE
                FORMER RTABLE IS RESTORED.
          NOTES      : THE BITS IN THIS BYTE ARE NOT SAVED WHEN A NEW RTABLE
                IS BEING LOADED, SINCE THE BITS DEFINED HERE ARE
                RTABLE INDEPENDENT.
