/	OS/8 FILE UTILITY PROGRAM.  ALLOWS EXAMINATION AND
/  MODIFICATION OF OS/8 MASS STORAGE DEVICES FROM THE CON-
/  SOLE.  DUMPING OF BLOCKS, LISTING OF WORDS AND MODIFICA-
/  TION OF WORDS CAN BE DONE IN 7 FORMATS: OCTAL; SIGNED AND
/  UNSIGNED DECIMAL; UNPACKED, 6-BIT PACKED, XS240 PACKED AND
/  OS/8 PACKED ASCII.  LISTING AND DUMPING CAN ALSO BE DONE
/  IN 5 MORE FORMATS: BCD, BYTE (OCTAL CHARACTER), 2 PSEUDO-
/  SYMBOLIC FORMATS [PDP-8 & FPP-12/8A], AND A COMBINATION
/  FORMAT FOR DIRECTORY DUMPING. PROGRAM USES BOTH COMMAND
/  WORDS AND COMMAND CHARACTERS (LIKE ODT) FOR DIRECTION.

/VERSIONS 1 THRU 4 - "XTAPE" FOR THE XSYSTEM,
/  LAST REVISION--APRIL 1970.
/
/VERSION 5 - OS/8 OPERATION, JULY 1972 THRU JUNE 1976
/  "(...)", "C & 'CC AS NUMBERS, IOT DECODING, LIST
/  & DUMP FORMATS, OUTPUT TO LPT:, FILE DATE & LOC
/  IN DIRECTORY, "WORD MEMREF...", BCD OUTPUT,
/  ADDITIONAL ODT OUTPUTS, "BYTE" OUTPUT.
/VERSION 6 - EXPANSION OF OS/8 OPERATION, JUNE 1976:
/  "FILLER" FOR "MODIFY", SEARCH LIMITS CHANGE, "WRITE"
/  WITH AN ARGUMENT, FPP INSTRUCTION DECODING, CHAINING
/  SUPPORT (FOR CCL CALLS), LOAD MODULE HANDLING AND
/  "SHOW HEADER", MULTIPLE DEFAULT EXTENSIONS, ^R FOR
/  RETYPE, SET REPLACES OPTION, NEW OUTPUT ROUTINE FOR
/  "DIRECTORY" FORMAT, LINK OVERLAY HANDLING, ODT CHANGES,
/  EXIT, SCAN, WRITE LOCKED OPERATION, SPEED UP SEARCHES,
/  XS240 FORMATS
/VERSION 6.17 - APR 1, 1977; BATCH OPERATION, COMMENT
/VERSION 6.20 - MAY 16, 1977; NEW DATE, FULL FILE OUTPUT
/   (SET/SHOW DDEV, OPEN ..., CLOSE), OPT ":" ON DEVICES.
/VERSION 6.21 - JUN 4, 1977; NEW INPUT ROUTINE, TEMP STORAGE
/VERSION 6.22 - JUL 13, 1977; CRTL-Q & -S, SCOPE MODE,
/  IF/END COMMANDS, ALPHA DATE.
/
/PREVIOUS VERSIONS HAVE BEEN AVAILABLE THROUGH DECUS,
/  DEC SUPPORT BEGINS WITH VERSION 7 - 20-JUL-77.
/		VERSION 7 PATCHES:
/		1.CTRL/U CRASH & OVERLAY MAPPING IN SAVE MODE(7A TO 7B)
/		2.FIXED SHOW CCB PROBLEM(7B TO 7C)
/		3.ODT MAPPING ON LD. MODULES(7C TO 7D)
/		4.ADDED SHOW CCB SUPPORT FOR KT8A SAVE IMAGES(7D TO 7E)
/	SOME ROUTINES AND IDEAS USED IN THIS PROGRAM WERE
/  DERIVED FROM EDIT-8 AND FOCAL, BY RICK MERRILL, DEC.
/	THE ODT COMMAND SET IS NEARLY IDENTICAL TO THE OS/8
/  ODT COMMAND SET EXCEPT THAT 15 BIT ADDRESSES ARE USED
/  EVERYWHERE AND THERE ARE NO COMMANDS FOR PROGRAM EXECU-
/  TION.
/	THE DOUBLE PRECISION ARITHMETIC ROUTINES ARE A MUCH
/  MODIFIED VERSION OF DECUS 8-115A.

/ 9-DEC-2018 LHN
/  DSN 35.13.1 applied here to correct the starting address
/              and job status word when assembling Futil.

/SUBROUTINE TO 'GET' A WORD FROM THE DEVICE.
/
/  THE ACTUAL WORD ON THE DEVICE THAT IS ACCESSED
/  IS DEPENDENT ON THE MODE SWITCH, AS FOLLOWS:
/
/  MODE		ACTION
/
/  0 = NORMAL	THE HIGH 7 BITS OF THE 15 BIT ADDRESS
/		ARE ADDED TO THE SPECIFIED BLOCK #
/		TO GET THE ACTUAL BLOCK & THE LOW 8
/		BITS OF THE 15 BIT ADDR ARE USED TO
/		SPECIFY THE WORD WITHIN THE BLOCK.
/
/ -1 = OFFSET	THE 12 BIT "OFFSET" (WHICH IS NEGATED)
/		IS ADDED TO THE LOW 12 BITS OF THE
/		ADDRESS, AND THEN THE NEW ADDRESS IS
/		HANDLED AS ABOVE.
/		THIS MODE IS USED PRIMARILY WHEN
/		WORKING WITH THE OPERATING SYSTEM
/		WITH OVERLAYS WHOSE REAL START BLOCK
/		AND LOCATION WITHIN A FIELD ARE KNOWN.
/		BY SETTING THE "OFFSET" TO THE START
/		ADDRESS OF THE OVERLAY, ITS REAL
/		ADDRESSES CAN BE USED AND THE PROPER
/		LOCATIONS WILL BE ACCESSED.
/
/ +1 = SAVE	THIS MODE IS USED WITH CORE IMAGE
/		"SAVE" FILES ONLY.  THE FILE'S CCB
/		(CORE CONTROL BLOCK) IS USED TO
/		DETERMINE THE REAL LOCATION ON THE
/		DEVICE OF THE SPECIFIED 15 BIT ADDR-
/		ESS.  THE START BLOCK OF THE FILE
/		IS USED, AND ANY SPECIFIED "BLOCK"
/		PART IS USED TO SPECIFY THE OVERLAY
/		WANTED AT THAT ADDRESS.  FOR FILES
/		WITHOUT OVERLAYS (GENERATED BY THE
/		MONITOR "SAVE" COMMAND), THIS PART
/		MUST BE ZERO (0) OR NO MATCH WILL
/		OCCUR.  FOR FILES WITH OVERLAYS
/		(GENERATED BY THE PROGRAM "LINK"),
/		A LEGAL OVERLAY AT THE SPECIFIED
/		ADDRESS MUST BE SPECIFIED FOR A
/		MATCH TO OCCUR.  THIS MODE CAN ONLY
/		BE USED AFTER A "FILE" COMMAND.
/
/ +2 = LOAD	THIS MODE IS USED WITH OS/8 FORTRAN
/		IV LOAD MODULES.  THE FILE'S HEADER
/		BLOCK IS USED TO DETERMINE THE REAL
/		LOCATION ON THE DEVICE OF THE SPECI-
/		FIED 15 BIT ADDRESS AND THE "BLOCK"
/		PART IS USED TO SPECIFY THE OVERLAY
/		WANTED AT THAT ADDRESS.  THIS MODE CAN
/		ONLY BE USED AFTER A "FILE" COMMAND.
