; 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.
;**;[63] Change documentation to comply with the monitor MDR 10-JUN-86
; POS DESCRIPTION
; --- --------
;
; 0 THIS ENTRY IS FUNCTIONALLY EQUIVALENT TO POSITION 1,
; BUT IT IS NOT USED BY THE MONITOR.
;
; 1 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
; ***This entry vector is used by the monitor at system startup.
;
; 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 SYSERR 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.
