WHILE ITS IS RUNNING, IT USUALLY DISPLAYS, ON THE BOTTOM BAY OF
LIGHTS ON THE PDP-10, WHICH JOB IS BEING RUN.  THE NUMBER OF THE LIT
UP BIT IS WHICH JOB IS CURRENTLY RUNNING.

ALL IMPLEMENTED SYMBOLIC
SYSTEM CALLS (SUCH AS OPEN AND DELETE)
ARE LISTED AS SIXBIT NAMES IN ITS AT THE TABLE CALLED SYSCTB:.  THE APPROPRIATE
LOCATIONS WHERE EACH OF THESE CALLS ARE EXECUTED ARE LISTED IN THE TABLE
CALLED SYSCTD:.  MOST OF THE CALLS HAVE SOME DOCUMENTATION IN THE ITS
LISTING VERY CLOSE TO THE ROUTINE THAT EXECUTES THE CALL.

THE ITS CODE THAT EXECUTES USER UUOS USUALLY STARTS WITH A TAG BEGINNING
WITH THE LETTER "A" AND AUGMENTED WITH THE NAME OF THE UUO.  FOR EXAMPLE,
TO LOOK AT THE CODE THAT HANDLES A .IOT, LOOK UP THE SYMBOL "AIOT".  OCCASIONALLY
THE SYMBOL STARTS WITH "N" RATHER THAN "A".  DISK ROUTINE PROCEDURES ALMOST
ALWAYS BEGIN WITH "Q", AND TELETYPE CODE WITH "TT".

USER VARIABLES ARE STORED SUCH THAT ALL THE VARIABLES FOR A SINGLE JOB
ARE TOGETHER.  THE SYMBOL "L" IS DEFINED EQUAL TO THE TOTAL SIZE
OF THE VARIABLE BLOCK.  HENCE, FOR EXAMPLE, THE UNAME OF THE JOB
WITH INDEX 30 IS STORED IN LOCATION UNAME+30*L.
WHILE ITS IS RUNNING THE JOB WITH INDEX N, ACCUMULATOR
U CONTAINS N*L.  WHEN ITS WANTS TO SCHEDULE(RUN) A CERTAIN JOB,
FIRST THAT JOB'S USTP MUST BE 0.  THEN, THAT JOBS FLSINS(FLUSH INSTRUCTION)
IS EXECUTED, AND THE JOB DOES NOT RUN UNLESS THE INSTRUCTION SKIPS.
THE FORMAT FOR EXECUTING A NEW SYSTEM CALL IS:

CALL:	.CALL CALBLK		;THE CALL ITSELF
	;ERROR RETURN IS TO CALL+1
	;SUCCESSFUL RETURN IS TO CALL+2


	...

CALBLK:	SETZ		;ALWAYS
	SIXBIT /NAME/		;WHERE "NAME" IS ANY IMPLEMENTED CALL
	ARG1		;ARGUMENTS START HERE
	ARG2

	...

	SETZ ARGN		;BIT 4.9 ON MEANS THIS ARG IS THE LAST ONE

A LIST OF ALL IMPLEMENTED SYSTEM CALLS MAY BE SEEN
IN DSK:SYSENG;ITS > STARTING AT SYSCTB:.  THE ACTUAL ADDRESSES WITHIN ITS
WHERE EACH CALL IS EXECUTED MAY BE FOUND FROM THE TABLE
STARTING AT SYSCTD:.

TYPES OF ARGS:

  THERE ARE THREE MAIN TYPES OF ARGS: INPUT, RESULT AND CONTROL BIT.
THEY ARE DISTINGUISHED BY BITS 4.2 AND 4.3 OF THE ARGUMENT WORD:
  4.3, 4.2 = 0  --  INPUT
	=1  --  RESULT
	=2  --  CONTROL BIT.
  THE ORDER OF THE INPUT ARGS MATTERS; SO DOES THE ORDER
OF THE RESULT ARGS. OTHER THAN THAT, THE ORDER IS IRRELEVANT.

INPUT ARGS:  MAY OR MAY NOT BE IMMEDIATE, ACCORDING TO BIT 4.1 .
  IN EITHER CASE, AN EFFECTIVE ADDRESS IS CALCULATED
FROM THE R.H., INDEX AND INDIRECT FIELDS.
IF THE ARG IS IMMEDIATE, THAT ADDRESS IS ACTUALLY PASSED TO THE
SYSTEM CALL; OTHERWISE, THE WORD AT THAT ADDRESS IS PASSED.
(EXCEPTION: SOME SYSTEM CALLS UPDATE THEIR INPUT ARGS.
THOSE ARGS USUALLY MAY NOT BE IMMEDIATE.)
THE VALUES OF THE INPUT ARGS GIVEN ARE PASSED IN ORDER TO
THE SYSTEM CALL, WHICH MAY NOT USE ALL OF THEM.
IF MORE THAN 8 INPUT ARGS ARE GIVEN, AN ERROR WITH STATUS CODE 15
IS INDICATED. FEWER ARGS THAN THE PARTICULAR CALL REQUIRES
RESULTS IN AN ERROR WITH CODE 30 .

RESULT ARGS:
  CANNOT BE IMMEDIATE. THE EFFECTIVE ADDRESS IS CALCULATED
AS USUAL, AND THE VALUE RETURNED BY THE SYSTEM CALL
IS STORED IN THE WORD AT THAT ADDRESS.
IF THERE ARE SEVERAL RESULT ARGS, EACH WILL GET THE NEXT
SUCCESSIVE VALUE RETURNED BY THE SYSTEM CALL. IF THERE ARE
MORE RESULT ARGS THAN THE SYSTEM CALL RETURNS VALUES,
JUNK WILL BE STORED IN THE EXCESS RESULT ARGS.
IF MORE VALUES ARE RETURNED THAN THERE ARE RESULT ARGS,
THE EXTRA VALUES WILL BE IGNORED.
MORE THAN 8 RESULT ARGS CAUSES AN ERROR RETURN.

CONTROL BIT ARGS: MAY OR MAY NOT BE IMMEDIATE.
  THE VALUES OF ALL CONTROL BIT ARGS GIVEN
ARE XOR'ED TOGETHER, AND THE RESULT MAY OR MAY NOT BE USED
BY THE SYSTEM CALL. ONLY THE RIGHT HALF OF A NON-IMMEDIATE
CONTROL BUT ARG IS SIGNIFICANT.
FAILURE-CODES RETURNED BY NEW SYSTEM CALLS (AND .OPEN'S, ETC.)

  THE FAILURE CODE FROM A NEW SYSTEM CALL THAT DOESN'T SKIP
CAN BE OBTAINED BY READING THE .BCH USET VARIABLE TO FIND THE
NUMBER OF THE CHANNEL ON WHICH THE CODE WAS RETURNED, AND THEN
READING THAT CHANNEL'S .IOC VARIABLE TO GET A WORD WITH THE ERROR
CODE IN BITS  3.1 - 3.6 .

THIS FILE LISTS ALL SYSTEM CALLS AND UUO'S.  EACH CALL IS LABELED
WITH ITS NAME.  THE LABELS IN PARENTHESIS ARE THE LOCATIONS OF
THE ACTUAL ROUTINES.  THE NUMBERS FOLLOWING THE SYSTEM LABELS ARE
THE PAGE AND LINE NUMBERS OF THE LABEL IN SYSENG;.  A PAGE NUMBER
WITH NO SPECIAL CHARACTER IN FRONT OF IT MEANS THAT IT IS IN ITS >

LABEL IS IN TS2TTY > (CURRENTLY 45); AND A '"' IN FRONT OF THE PAGE
NUMBER MEANS THAT THE LABEL IS IN MTAPE > (CURRENTLY 51).
