# RESTART TABLES
# --------------
#
# THERE ARE TWO FORMS OF RESTART TABLES FOR EACH GROUP.  THEY ARE KNOWN AS THE EVEN RESTART TABLES AND THE ODD
# RESTART TABLES.  THE ODD TABLES HAVE ONLY ONE ENTRY OF THREE LOCATIONS WHILE THE EVEN TABLES HAVE TWO ENTRIES
# EACH USING THREE LOCATIONS. THE INFORMATION AS TO WHETHER IT IS A JOB, WAITLIST, OR A LONGCALL IS GIVEN BY THE
# WAY THINGS ARE PUT INTO THE TABLES.
#
# A JOB HAS ITS PRIORITY STORED IN PRDTTAB OF THE CORRECT PHASE SPOT - A POSITIVE PRIORITY INDICATES A
# FINDVAC JOB, A NEGATIVE PRIORITY A NOVAC.  THE 2CADR OF THE JOB IS STORED IN THE CADRTAB.
# FOR EXAMPLE,
#
#		5.7SPOT		OCT	23000
#				2CADR	SOMEJOB
#
# A RESTART OF GROUP 5 WITH PHASE SEVEN WOULD THEN CAUSE SOMEJOB TO BE RESTARTED AS A FINDVAC WITH PRIORITY 23.
#
#		5.5SPOT		OCT	-23000
#				2CADR	ANYJOB
#
# HERE A RESTART OF GROUP 5 WITH PHASE 7 WOULD CAUSE ANYJOB TO BE RESTARTED AS A NOVAC WITH PRIORITY 23.
# A LONGCALL HAS ITS GENADR OF ITS 2CADR STORED NEGATIVELY AND ITS BBCON STORED POSITIVELY.  IN ITS PRDTTAB IS
# PLACED THE LOCATION OF A DP REGISTER THAT CONTAINS THE DELTA TIME THAT LONGCALL HAD BEEN ORIGINALLY STARTED
# WITH.  EXAMPLE,
#
#		3.6SPOT		GENADR	DELTAT
#				-GENADR	LONGTASK
#				BBCON	LONGTASK

#				OCT	31000
#				2CADR	JOBAGAIN
#
# THIS WOULD START UP LONGTASK AT THE APPROPRIATE TIME, OR IMMEDIATELY IF THE TIME HAD ALREADY PASSED. IT SHOULD
# BE NOTED THAT IF DELTAT IS IN A SWITCHED E BANK, THIS INFORMATION SHOULD BE IN THE BBCON OF THE 2CADR OF THE
# TASK.  FROM ABOVE, WE SEE THAT THE SECOND PART OF THIS PHASE WOULD BE STARTED AS A JOB WITH A PRIORITY OF 31.
#
# WAITLIST CALLS ARE IDENTIFIED BY THE FACT THAT THEIR 2CADR IS STORED NEGATIVELY.  IF PRDTTAB OF THE PHASE SPOT
# IS POSITIVE, THEN IT CONTAINS THE DELTA TIME, IF PRDTTAB IS NEGATIVE THEN IT IS THE -GENADR OF AN ERASABLE
# LOCATION CONTAINING THE DELTA TIME, THAT IS, THE TIME IS STORED INDIRECTLY.  IT SHOULD BE NOTED AS ABOVE, THAT
# IF THE TIME IS STORED INDIRECTLY, THE BBCON MUST CONTAIN THE NECESSARY E BANK INFORMATION IF APPLICABLE.  WITH
# WAITLIST WE HAVE ONE FURTHER OPTION, IF -0 IS STORED IN PRDTTAB, IT WILL CAUSE AN IMMEDIATE RESTART OF THE
# TASK.  EXAMPLES,
#
#				OCT	77777		# THIS WILL CAUSE AN IMMEDIATE RESTART
#				-2CADR	ATASK		# OF THE TASK :ATASK:
#
#				DEC	200		# IF THE TIME OF THE 2 SECONDS SINCE DUMMY
#				-2CADR	DUMMY		# WAS PUT ON THE WAITLIST IS UP, IT WILL BEGIN
#							# IN 10 MS, OTHERWISE IT WILL BEGIN WHEN
#							# IT NORMALLY WOULD HAVE BEGUN.
# Page 212
#				-GENADR	DTIME		# WHERE DTIME CONTAINS THE DELTA TIME
#				-2CADR	TASKTASK	# OTHERWISE THIS IS AS ABOVE
#

# PROGRAM DESCRIPTION: NEWPHASE						DATE:  11 NOV 1966
# MOD: 1								ASSEMBLY:  SUNBURST REV
# MOD BY: COPPS								LOG SECTION: PHASE TABLE MAINTENANCE
# FUNCTIONAL DESCRIPTION:
#
#	NEWPHASE IS THE QUICK WAY TO MAKE A NON VARIABLE PHASE CHANGE. IT INCLUDES THE OPTION OF SETTING
#	TBASE OF THE GROUP.  IF TBASE IS TO BE SET, -C(TIME1) IS STORED IN THE TBASE TABLE AS FOLLOWS:
#
#		(L-1)	TBASE0
#		(L)	TBASE1	(IF GROUP=1)
#		(L+1)
#		(L+2)	TBASE2	(IF GROUP=2)
#		-----
#		(L+6)	TBASE4	(IF GROUP=4)
#		(L+7)
#		(L+8)	TBASE5	(IF GROUP=5)
#
#	IN ANY CASE, THE NEGATIVE OF THE PHASE, FOLLOWED (IN THE NEXT REGISTER) BY THE PHASE, IS STORED IN THE
#	PHASE TABLE AS FOLLOWS:
#
#		(L)	-PHASE1	(IF GROUP=1)
#		(L+1)	PHASE1
#		(L+2)	-PHASE2	(IF GROUP=2)
#		(L+3)	PHASE2
#		-----
#		(L+7)	PHASE4
#		(L+8)	-PHASE5	(IF GROUP=5)
#		(L+9)	PHASE5
#
# CALLING SEQUENCE:
#	EXAMPLE IS FOR PLACING A PHASE OF FIVE INTO GROUP THREE:
#
#	1) IF TBASE IS NOT TO BE SET:
#			L-1	CA	FIVE
#			L	TC	NEWPHASE
#			L+1	OCT	00003
#
#	2) IF TBASE IS TO BE SET:
#			L-1	CS	FIVE
#			L	TC	NEWPHASE
#			L+1	OCT	00003
#
# SUBROUTINES CALLED: NONE
#
# NORMAL EXIT MODE: AT L+2 OF CALLING SEQUENCE
#
# ALARM OR ABORT EXITS: NONE
#
# OUTPUT: PHASE TABLE AND TBASE TABLE UPDATED
#
# ERASABLE INITIALIZATION REQ'D: NONE
# Page 221
# DEBRIS:  A,L,TEMPG
