PROPCOM DSECT
Cross Reference (Contains links to field and bit definitions)
PROPCOM Prolog
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.

NOTES : THE BITS IN THIS BYTE ARE SAVED WHEN LOADING A NEW ROUTING
TABLE AND RESTORED IF AN ERROR IS DETECTED 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.
