; THIS PROGRAM IS RUN BY JOB 0 TO PERFORM VARIOUS USER-MODE
; FUNCTIONS THAT AFFECT THE OPERATION OF THE SYSTEM

; DEPENDING UPON THE DESIRED ACTION, THE PROGRAM IS STARTED AT
; ONE OF SEVERAL POSITIONS IN ITS ENTRY VECTOR.

; POS	DESCRIPTION
; ---	--------
;
;  0	CALLED ONCE DURING SYSTEM STARTUP BY RUNDD ROUTINE IN MEXEC.
;	READS FILE "SYSTEM:x-CONFIG.CMD" FOR COMMANDS:
;	  CHANGE - set accounting shift change times
;	  DEFINE - define system-wide logical names
;	  ENABLE/DISABLE account validation
;	  ENABLE/DISABLE directory-parameter setting by non-priv users
;	  ENABLE/DISABLE use of hardware disk optimization feature
;	  ENABLE/DISABLE magtape drive assignment by MTCON
;	  HOST - set ARPANET host number of this CPU
;	  MAGTAPE - logical magtape units (e.g. MTA3:) with
;		actual serial numbers
;	  NODE - set DECNET node name and number for this CPU
;	  PRINTER - load VFU and RAM files and set lowercase attribute
;	  TERMINAL - set auto-baud, nobell, remote, and speed
;		attributes of terminals
;	  TIMEZONE - set time zone for this site
;
;  1	THIS ENTRY IF FUNCTIONALLY EQUIVALENT TO POSITION 0,
;	BUT IT IS NOT USED BY THE MONITOR.
;
;  2 	CONTAINS PROGRAM VERSION NUMBER.
;
;  3	CALLED BY RUNDD ROUTINE IN MEXEC DURING SYSTEM
;	INITIALIZATION AFTER A CRASH TO:
;	1. Copy PS:<SYSTEM>DUMP.EXE to PS:<SYSTEM>DUMP.CPY
;	2. Extract unrecorded SPEAR entries from DUMP.EXE and
;	   log them using the SYERR JSYS
;
;  4	CALLED BY CHKR ROUTINE IN MEXEC WHILE SYSTEM IS RUNNING
;	WHENEVER PHYSIO DETECTS THAT A TAPE DRIVE HAS COME ONLINE
;	AND PHYSIO DIDN'T KNOW ABOUT THE DRIVE AT SYSTEM STARTUP.
;	THE CONFIG FILE IS READ AS IF ENTERED AT ENTRY VECTOR
;	POSITION 0, EXCEPT ONLY THE "MAGTAPE" COMMANDS IN THE
;	FILE ARE PROCESSED; ALL OTHER COMMANDS ARE IGNORED.
