+Historical footnote: DDT was developed at MIT for the
+PDP-1 computer in 1961. At that time DDT stood for "DEC
+Debugging Tape". Since then, the idea of an on-line
+debugging program has propagated throughout the computer
+industry. DDT programs are now available for all DEC
+computers. Since media other than tape are now frequently
+used, the more descriptive name "Dynamic Debugging Technique"
+has been adopted, retaining the DDT acronym. Confusion
+between DDT-10 and another well-known pesticide, dichloro-
+diphenyl-trichloroethane (C  H Cl ), should be minimal since
+			   14 9  5
+each attacks a different, and apparently mutually exclusive,
+class of bugs.

+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 .
