DESCRIPTIONS OF INDIVIDUAL SUBROUTINES.


		ACMSRT

PURPOSE		TO SORT A SINGLE DIMENSIONAL ARRAY INTO ASCENDING
	ORDER.

USAGE		CALL ACMSRT(VECTOR,N)
	WHERE	VECTOR	IS THE SINGLE DIMENSIONAL ARRAY( A VECTOR)
			TO BE SORTED.
		N	IS THE NUMBER OF ELEMENTS TO BE SORTED IN THE
			ARRAY. N IS LIMITED BY THE AMOUNT OF CORE
			AVAILABLE TO THE PROGRAM, AND BY THE PROGRAM.
			(IF CORE IS AVAILABLE, N MAY BE AS LARGE AS
			2**17-1)  20000 NUMBERS MAY BE SORTED IN
			APPROXIMATELY 3.5 SECONDS OF CPU TIME.

METHOD		ORDERING IS BY INTEGER SUBRACTION.  PROGRAM TAKEN
		FROM JOURNAL OF THE ASSOCIATION OF COMPUTING MACHINERY.

************************************************************************


		ALLCOR

PURPOSE:	DYNAMICALLY ALLOCATE CORE FOR USE BY A FORTRAN PROGRAM.
	THIS ALLOWS A PROGRAM TO HANDLE LARGE PROBLEMS WITHOUT HAVING TO
	RESERVE THAT MUCH SPACE WHEN THE PROGRAM WAS LOADED, THUS
	PENALIZING USERS WHO DON'T NEED THAT MUCH SPACE AND ALSO HURTING
	SYSTEM THROUGHPUT.

USAGE:		CALL ALLCOR(MAX,IERR,IREL,SPACE(1))
	WHERE	MAX:	TOTAL AMOUNT OF STORAGE TO BE RESERVED.
		IERR:	IS ERROR CODE RETURNED.
			IERR=0 NO ERROR.
			IERR=1 WARNING! CORE OBTAINED BUT NO MORE IS
				AVAILABLE, OR MAX<0.  MAY RESULT IN FATAL ERROR
				LATER IN RUN.
			IERR=-1 CORE NOT AVAILABLE.
		IREL:	SUBSCRIPT ON SPACE SUCH THAT SPACE(IREL) IS
			FIRST LOCATION IN ALLOCATED CORE. OTHER ARRAYS
			(BEYOND FIRST) ARE AT SPACE(IREL+LENGTH1),
			SPACE(IREL+LENGTH1+LENGTH2),ETC. WHERE LENGTHN IS
			 SIZE IN WORDS OF THE NTH ARRAY.  REMEMBER THAT DOUBLE
			 PRECISION AND COMPLEX ARRAYS USE TWO WORDS PER ENTRY.
		SPACE:	A ONE ELEMENT ARRAY WHICH ALL ALLOCATED CORE
			IS TO BE ADDRESSED RELATIVE TO. (MUST BE SINGLE PRECISION)

	THIS ROUTINE MAY OPERATE IN EITHER OF TWO MODES.  ON A NON-
	VIRTUAL MEMORY SYSTEM, IT WILL ATTEMPT TO ALLOCATE CORE IN THE
	PROGRAMS HIGH SEGMENT.  THIS REQUIRES THAT EITHER FOROTS
	BE FORCED TO LOAD INTO THE LOW SEGMENT, SO THAT THERE IS NO
	HIGH SEGMENT AT ALL, OR CREATING A NON-SHAREABLE HIGH SEGMENT
	AS PART OF THE PROGRAM (IT CANNOT BE GETSEGED).  IF A
	WRITEABLE HIGH SEGMENT CAN NOT BE CREATED, OR THE HIGH SEGMENT
	WHICH EXISTS CAN NOT BE WRITE ENABLED, ALLCOR WILL PRINT THE
	MESSAGE "CANNOT WRITE ENABLE HIGH SEGMENT DATA AREA".  THE LOAD
	COMMAND FOR A PROGRAM USING THIS FORM OF ALLCOR IS

LOAD %'SEG:LOW' FILE-SPEC,FILE-SPEC,...,SYS:FORLIB/LIB

	IF LINK-10 IS USED, OR IF LOADER IS USED,

LOAD %H FILE-SPEC,FILE-SPEC,...,SYS:FORLIB/LIB

	IF THE PROGRAM IS RUN ON A VIRTUAL MEMORY SYSTEM, AND FOROTS
	HAS BEEN MODIFIED TO UNDERSTAND PAGING(AS IT HAS AT W.M.U.)
	ALLCOR WILL ALLOCATE CORE IN THE FORM OF PAGES.  THE PAGES
	WILL HAVE ADDRESSES IMMEDIATELY ABOVE THE HIGH SEGMENT (IF
	ONE EXISTS) BUT ARE CONSIDERED TO BE NON-CONTIGUOUS LOW SEGMENT
	PAGES (WHICH IS WHY FOROTS HAS TO UNDERSTAND).  THIS ALLOWS THE
	USE OF THE SHAREABLE FOROTS, WHICH IMPROVES PERFORMANCE OF THE SYSTEM.
	IF FOROTS HAS NOT BEEN MODIFIED, ALLCOR WILL BEHAVE AS THOUGH THE SYSTEM
	WAS A NON-VIRTUAL MEMORY SYSTEM.  NO SPECIAL LOADING INSTRUCTIONS
	ARE NECESSARY IF THE PAGING FORM OF ALLCOR IS TO BE USED.

		IPROG:	PROGRAMMER NUMBER(IN OCTAL) RETURNED.


************************************************************************

		GTCORE

PURPOSE:	TO ALLOCATE CORE IN THE LOW SEGMENT DYNAMICLY USING
	FOROTS.  THIS IS DESIREABLE SINCE IT PERMITS USE OF THE
	SHAREABLE FOROTS HIGH SEGMENT.

USAGE:		CALL GTCORE(IWORDS,BASE,IOFFST,IERR)
   OR:		CALL GTCORE(IWORDS,BASE,IOFFST,IERR,IRESV)

	WHERE
		IWORDS - NUMBER OF WORDS OF CORE TO ALLOCATE.
		BASE   - ARRAY RELATIVE TO WHICH ALLOCATED CORE IS TO
			 BE ADDRESSED.
		IOFFST - BASE OFFSET INTO ARRAY TO GET FIRST ALLOCATED
			 WORD.
		IERR   - ERROR CODE.
				VALUE	MEANING
				  0	NO ERROR. CORE ALLOCATED.
				 -1	INSUFFICIENT CORE.
				  1	INSUFFICIENT CORE TO ALLOCATED RESERVE.
					 IWORDS ALLOCATED.
		IRESV  - NUMBER OF WORDS TO RESERVE FOR FOROTS (IN ONE CHUNK)
			  THIS ARGUMENT IS OPTIONAL.

NOTES:	THIS CORE ALLOCATION ROUTINE IS USED SIMILARY TO ALLCOR.  HOWEVER,
	CORE IS ALLOCATED IN THE LOW SEGMENT, AND MUST BE GIVEN BACK TO
	FOROTS BEFORE A IT CAN BE REALLOCATED.  ADDITIONAL ALLOCATIONS
	MAY BE MADE INDEPENDENTLY, BUT THE OFFSET OF EACH MUST
	BE REMEMBERED SO THAT THE CORE MAY BE RETURNED.  FREQUENT REALLOCATIONS
	SHOULD BE AVOIDED, SINCE CORE MAY BECOME FRAGMENTED MAKING IT
	IMPOSSIBLE TO GET THE DESIRED AMOUNT OF CORE IN ONE BLOCK.

	THIS ROUTINE WORKS WELL WITH CHAINB, BUT NOT WITH LINK-OVERLAYS.
	THIS IS BECAUSE LINK-OVERLAYS DO NOT PREALLOCATE THEIR CORE
	AND THE CORE REQUIRED FOR A NON-RELOCATABLE OVERLAY MAY BE TAKEN
	BY GTCORE, MAKING THE PROGRAM NON-RUNNABLE.
	THIS PROBLEM CAN BE REDUCED BY ENSURING THAT THE LARGEST OVERLAY
	IS IN CORE WHENEVER GTCORE IS CALLED.  IF THIS IS DONE, THE SITUATION
	WILL REDUCE TO APPROXIMATELY WHAT IT WOULD BE IF GTCORE WERE
	NOT BEING USED.  HOWEVER, THE PROGRAM MAY STILL BOMB BECAUSE
	FOROTS HAS TAKEN CORE THAT AN OVERLAY NEEDS.
