## Purpose:	A section of Luminary 1C, revision 131.
##		It is part of the source code for the Lunar Module's (LM)
##		Apollo Guidance Computer (AGC) for Apollo 13.
##		This file is intended to be a faithful transcription, except
##		that the code format has been changed to conform to the
##		requirements of the yaYUL assembler rather than the 
##		original YUL assembler.

## Website:	www.ibiblio.org/apollo/index.html
## Mod history:	05/06/03 RSB.	Began transcribing.
##		05/14/05 RSB	Corrected website references above.
##		2017-01-06 RSB	Page numbers now agree with those on the
##				original harcopy, as opposed to the PDF page
##				numbers in 1701.pdf.
##		2017-02-08 RSB	Comment-text fixes identified while proofing Artemis 72.
##		2017-02-20 RSB	Proofed comment text using octopus/ProoferComments.
##		2017-03-01 RSB	Restored a period which was present in both Luminary 116
##				and 210, and was therefore presumably missing due to a 
##				printer problem.
##		2017-03-13 RSB	GOP00FIX -> GOPOOFIX.

# 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 IN TO 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
#
## In the line below, the printout certainly has no period at the end of the line.  However,
## the corresponding lines in Luminary 116 and 210 have such a period and are otherwise identical.  
## Therefore, this is presumably a printer error, and the period has been restored.
# 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 INFORMATOIN SHOULD BE IN THE BBCON OF THE 2CADR OF THE
# TASK.  FROM ABOVE, WE SEE THAT THE SECOND PART O FTHIS 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 WAITLIST IS UP, IT WILL BEGIN
#							IN 10 MS, OTHERWISE IT WILL BEGIN WHEN
#							IT NORMALLY WOULD HAVE BEGUN.
