***** Begin Version 7 *****

3000	CDM	19-Oct-81
	Added character routines ADJC1., ADJCG.

3001	AHM	2-Oct-81
	Make ADJ1.  and  ADJG.  work under  extended addressing.   Also,
	redefine array dimension field from 777B8 to 177B8 so that array
	bounds checking blocks  in section  0 will  hopefully look  more
	like the final version to be redefined for extended  addressing.
	Finally, create a PROTA. entry point which is the same as PROAR.
	for now to match the symbol that FORTRA 7(1250) requests.

3025	AHM	18-Nov-81
	Fix a bug in the trailing space edit to DATE (2020) that I  introduced
	when merging it into the V7 sources, and change two MOVEIs to  XMOVEIs
	for extended addressing support for good measure.

3052	AHM	1-Mar-82
	Make PROAR. work for extended addressing by widening the  flag
	field in  the dimension  block to  the upper  4 bits.   Delete
	PROTA. entry  point  since  it  is  not  needed  for  extended
	addressing after all.

3066	RVM	27-Mar-82
	Fix ADJ1., ADJG., ADJC1., and ADJCG. to not calculate the size
	of assumed-size arrays.

3073	JLC	31-Mar-82
	Remove RELEAS routine; it was for F40.

3122	JLC	28-May-82
	Segment FORMSC. Changed LERRs to $FCALLs, and move error msgs
	to a separate module FORMSL in FORMSC.

3124	AHM	6-Jun-82
	Added a SEGMENT  macro to  FDDT so that  everything goes  into
	.CODE. and .DATA.  under FTXLIB.  Also, preserve T1 around the
	PSOUT for "%FORDDT not loaded" under Tops-20.

3125	JLC	3-Jun-82
	Moved the error character to the beginning of the error macro
	calls.

3131	JLC	11-Jun-82
	Allow character string argument for ERRSNS error string return.

3132	CKS	11-Jun-82
	Add PROSB. to do substring bounds checking.

3140	JLC	2-Jul-82
	Fix ERRSET so that -1 for error number gets the entire table
	instead of just the V6-defined traps.

3141	JLC	2-Jul-82
	Install FFUNIT.

3142	AHM	3-Jul-82
	Install PRGEND in FFUNIT.

3161	JLC	16-Aug-82
	Fixed ERRSNS for extended addressing multi-sections.

3165	JLC	28-Aug-82
	Separate bounds check errors from others.

3205	AHM	18-Nov-82
	Insert error message texts for  TMA, CGP, CRP, NSS, CFS,  CGS.
	Change VDM and ICF to "Should not happen" errors.  Reword AQS.

3206	CDM	5-Nov-82/17-Jan-83
	Allow character arguments for DATE and TIME.

3257	AHM	14-Jan-83
	Fix DUMP  and PDUMP  -  FUNCT macro  made OTSZERWRD  I/O  list
	elements non-zero, FIN word was in wrong half of an I/O  list,
	change positional OUT. argument lists to keyword form, correct
	change in carriage control semantics between V6 and V7.

***** End V7 Development *****

3311	AHM	21-Apr-83
	The dummy FDDT module that resolves XCT FDDT.## requests  from
	/DEBUG:TRACE when FORDDT isn't loaded was in the hiseg instead
	of the lowseg.   Unfortunately, FDDT. contains  self-modifying
	code, and write-locking the high segment made it die.

3322	TGS	6-Jun-83	SPR:20-19252
	Calling ERRSET with a subroutine argument not declared EXTERNAL
	in the calling program unit jumps into an empty variable when 
	the user subroutine is called. Test for this case and ABORT if so.

3362	TGS	28-Oct-83	SPR:20-19293
	New TOPMEM and SRTINI calls to set ENDP/STARTP to force memory
	allocation from a user-supplied page number downward and, for
	SRTINI, preallocate pages 600:677 for SORT.  Insert new error
	messages for IPN (Illegal page number) and CPP (Can't preallocate
	pages) errors.

3405	TGS	24-Jan-84	SPR:20-19857
	TIME subroutine will round minutes early (09:13 59.6 to 09:14 59.9
	if called in a loop, for example.)  Do not use ODTIM% to return
	hours and minutes, since this JSYS uses a totally different algorithm
	for rounding on minute boundaries.

3407	TGS	31-Jan-84	SPR:20-19929
	QUIETX should suppress library routine error summaries as well as
	CPU summaries. (FORMSC comment change only).


***** Begin Version 10 *****

4007	RJD	24-Mar-83
	Eliminate extra PUSH and POP in OVLP.

4012	PLB	1-Jun-83
	Fix ERRSET to work with user code and OTS in different sections.

4023	JLC	23-Jun-83
	Search MTHPRM also.

4030	PLB	6-Jul-83
	Fix OVERFL to remove AOBJN & BLT.

4044	JLC	19-Sep-83
	Changed F.MED so it uses $N for the subroutine name, and
	thus can be called by any subroutine.

4060	JLC	1-Nov-83
	Removed EXTEND error messages, mistakenly placed (by me)
	in FORMSL.

4065	JLC	6-Dec-83
	Add subroutine PA1050 to allow PA1050 in core for V10
	programs running on TOPS-20.

4074	RVM	28-Jan-84
	Add the Mil. Spec/VAX FORTRAN bit manipulation functions.

4100	MRB	9-Feb-84
	Added code to do compatibility flagging in FORLIB. Outputs
	a warning message for usage of non compatible language features
	like CALLing an external function.

4101	CDM	16-Feb-84
	Create and expand the  character stack differently when  running
	in extended addressing.   Give the stack  its own section(s)  so
	that it has plenty of room.  Also add user subroutine ALCCHR.

4110	CDM	8-Mar-84
	Reworked DUMP  and  PDUMP  to work  under  extended  addressing.
	Changed how the  AC's are stored  to be dumped  out (used to  be
	stored  on  the  stack,  with  AC's  being  PUSH-ed  and  POP-ed
	everywhere, even though this is a subroutine and doesn't need to
	preserve any AC's).  Corrected I/O calls  to the ots to work  in
	non-zero sections.  For  now, not  giving both  upper and  lower
	bounds for  dumping  will  give  a  warning  message.   Lots  of
	comments added.  Grouped  together argument lists  to make  them
	look coherent.  Changed  "-" to  "///" in  format statements  to
	make then standard conforming (/FLAG will flag this).

4121	AHM	30-Apr-84
	Made QUIETX use HELLO macro, since it is now user callable,
	and supported.
	Module:	FORMSC

4130	MRB	6-Jun-84
	Add check for compatibility flagger to routine FFUNIT.

4155	JLC	2-Oct-84
	Moved %SVCNV, a routine to manipulate symbol table pointers,
	to here so it can be accessed by FORDDT with OTS:SHARE, the
	LINKing of sharable FOROTS, and OTS:NONSHARE.
	Separate system-dependent code in %SVCNV.

4162	RVM	2-Nov-84
	Define VAX FORTRAN INTEGER*2 and INTEGER*4 INTRINSIC function names.

4163	RVM	2-Nov-84
	Define the undotted names of the bit functions.

4165	MRB	15-Nov-84
	Change the equates for the undotted names to the dotted names
	to equate 30 bit addresses instead of just 18 bit addresses.

4170	JLC	19-Nov-84
	Fix FORSYM: put in a SEGMENT CODE so the code isn't obliterated
	on TOPS-10.

4171	JLC	29-Nov-84
	Fix some documentation in ERRSET.

4172	MRB	4-Dec-84
	Fix-up some flagger stuff for the routines DATE, TIME, ERRSET, 
	ERRSNS. 

4174	JLC	9-Jan-85
	Fix %SVCNV for symbol tables up to 511 pages as IOWDs.

4206	CDM	29-Mar-85	QAR 853072
	Fix ISHFTC to work correctly when rotate index is negative.

4207	CDM	29-Mar-85	QAR 853038
	Add SECNDS function for VMS compatability.

; Routine to perform FORTRAN array bounds checking at run time.

; Called with an argument block of the form:
;	-------------------------------------------------
;	!1!0!			! PTR TO SEQ NUMB OF ST	!
;	-------------------------------------------------
;	!1!0!			! PTR TO DIMENSION INF	!
;	-------------------------------------------------
;	!1!0!			! PTR TO 1ST SUBSCRIPT	!
;	-------------------------------------------------
;	!1!0!			! PTR TO 2ND SUBSCRIPT	!
;			     Etc.
;
; Where dimension information is represented by a block of the form:
;	-------------------------------------------------
;	!  		ARRAY NAME (IN SIXBIT)		!
;	-------------------------------------------------
;	!1!0! DIM CT !     !I!	! BASE ADDRESS		!
;	-------------------------------------------------
; V6	!A!F!0!0!		! PTR TO OFFSET		!
; V7	!1!0!A!F!		! PTR TO OFFSET		!
;	-------------------------------------------------
;	!1!0!			! PTR TO 1ST LOWER BND	!
;	-------------------------------------------------
;	!1!0!			! PTR TO 1ST UPPER BND	!
;	-------------------------------------------------
;	!1!0!			! PTR TO 1ST FACTOR	!
;	-------------------------------------------------
;	!1!0!			! PTR TO 2ND UPPER BND	!
;
;			     ETC
;   WHERE A IS A FLAG FOR "ADJUSTABLY DIMENSIONED ARRAY"
;	F IS A FLAG FOR "FORMAL ARRAY"
;
; Note that  the argument  list  is created  in the  compiler  routine
; PROARRXPN in the file ARRXPN.BLI and the dimension block is  created
; and written in CGDIMBLK in DEBUG.BLI.
;
;COMPUTES THE ADDRESS OF THE SPECIFIED ARRAY ELEMENT AND
; RETURNS THAT ADDRESS IN AC 0. IF ANY OF THE BOUNDS ARE
; EXCEEDED, AN ERROR MESSAGE IS GIVEN BEFORE PROCEEDING
;THE ADDRESS OF THE ARRAY ELEMENT IS COMPUTED BY THE
; FORMULA:
;	BASE ADDR + OFFSET + (1ST SS)*(1ST FACTOR) +
;		(2ND SS)*(2ND FACTOR) + .....
;IF AN ARRAY IS NOT A FORMAL, THE BASE ADDR+OFFSET WILL BE ADDED
; IN TO THE RESULT OF THIS ROUTINE BY THE FORTRAN PROGRAM CALLING
; THIS ROUTINE - THEREFORE THESE 2 TERMS ARE NOT INCLUDED IN THE RESULT
; UNLESS THE ARRAY IS FORMAL.
;IF AN ARRAY IS ADJUSTABLY DIMENSIONED, THE "OFFSET" CALCULATED UPON
; ENTRY TO THE SUBROUTINE IN WHICH THE ARRAY IS DECLARED ALREADY
; INCLUDES THE BASE ADDRESS - THEREFORE FOR ADJUSTABLY DIMENSIONED
; ARRAYS NEED NOT HAVE THE BASE ADDRESS ADDED IN SEPARATELY.

; Note that there are two formats for the adjustably dimensioned array
; and formal array flags.  The old format used for V6 and before  used
; the two high  order bits  of the flag  word.  The  pattern "10"  was
; illegal for  V6 because  it means  "adjustably dimensioned  but  not
; formal" -  a  non-sequitur for  Fortran.   Which is  just  as  well,
; because the two high order bits of the flag word had to be forced to
; "10" for V7  in order to  make the  flag word an  IFIW for  extended
; addressing.  The definitions of the bits were just shifted over by 2
; places for extended addressing.

;++
; FUNCTIONAL DESCRIPTION:
;
;	Both DUMP and PDUMP  output core to a  line printer between  the
;	optional locations passed by the user.  DUMP calls "EXIT."  when
;	done, while PDUMP  returns to  the users program.   The code  is
;	shared, ENTFLG is used  to determine whether  DUMP or PDUMP  was
;	entered.
;
;	First to be dumped are following PC flags and then the  contents
;	of the accumulators.
;
;		AR OV FLAG
;		AR CRY0 FLAG
;		AR CRY1 FLAG
;		PC CHANGE FLAG - FLOATING OVERFLOW
;		BIS FLAG
;
;	Following this are any memory locations the user has specified.
;
;	If a group of memory locations have the same contents, DUMP  and
;	PDUMP will finish printing the  current line, then indicate  the
;	repeated locations by:
;
;		Locations xx through yy contain zz
;
; CALLING SEQUENCE:
;
;	CALL DUMP(A(1),B(1),F(1), ... ,A(n),B(n),F(n))
;	CALL PDUMP(A(1),B(1),F(1), ... ,A(n),B(n),F(n))
;
; INPUT PARAMETERS:
;
;	Arguments are in triplets, each triplet taken separately.
;
;	A(n)	First element to be dumped.
;
;	B(n)	Last element to be dumped.
;
;		If the last two arguments, B(n) and F(n), are missing an
;		octal dump is made from A(n) to the end of user area.
;
;	F(n)	Mode to dump the elements in.
;	
;			0	octal		(O12 format)
;			1	floating point	(G12.5 format)
;			2	integer		(I12 format)
;			3	ascii		(A12 format)
;			4	double precision (G25.16)
;
;		An illegal or missing mode assignment causes the dump to
;		be made in octal.
;
;	where A, B, and F are optional sets of triplet arguments.
;
;	If no arguments  are given, the  entire user area  is dumped  in
;	octal.  Under extended  addressing, both A(n)  and B(n) must  be
;	given.
;
; IMPLICIT INPUTS:
;
;	None
;
; OUTPUT PARAMETERS:
;
;	None
;
; IMPLICIT OUTPUTS:
;
;	None
;
; FUNCTION VALUE:
;
;	None
;
; SIDE EFFECTS:
;
;	Used as Fortran subroutine, does NOT save AC values.

;This subroutine returns the time of day in two single word arguments or
;a character variable.
;
;The first argument gets  the hour and minute,  and the optional  second
;argument gets the second and tenth of a second.

;The first argument is given in military time:
;	02:15	(for a.m. time)
;	14:15	(for p.m. time)
;
;The optional second argument is of the form:
;	37.4

;The routine is called in the following manner:
;	XMOVEI	L,ARGBLK
;	PUSHJ	P,TIME

;ON THE -10, TIME OBTAINS THE TIME FROM THE MONITOR IN THE FORM:
;	TIME=THE NUMBER OF MILLISECONDS SINCE MIDNIGHT.

;ON THE  -20,  TIME OBTAINS  THE  INTERNAL  TIME FROM  THE  MONITOR  AND
;	CONVERTS IT  INTO MILLISECONDS  SINCE  MIDNIGHT, DOES  THE  SAME
;	CONVERSION FROM THERE AS ON THE -10, BUT ALSO HAS TO CORRECT FOR
;	GREENWICH MEAN TIME WHICH IS THE  TIME THE -20 INTERNAL TIME  IS
;	STORED IN.

	SUBTTL	CHRIS SMITH/CKS		8-Jun-82
				;[3132] New 

;Routine to perform substring bounds checking.

;The compiler transforms the substring reference
;
;	VAR(LB:UB)
;
;into
;
;	VAR(LB: PROSB.(VAR,LB-1,UB,ISN,'VAR') )
;
;where PROSB. checks the validity of LB and UB, then returns UB.  If the bounds
;are invalid, a warning message is typed.  (LB-1 is used instead of LB because
;LB-1 is conveniently available in the compiler's internal representation of
;substrings.)

;The conditions for valid substring bounds are
;
;	LB .LE. UB
;	LB .GE. 1
;	UB .LE. LEN(VAR)
;
;If a bound is found to be out of range, a warning message is typed.  No
;attempt at correction is made - the program will get the same results as if
;/DEBUG:BOUNDS were not specified, except for the message.

; FUNCTIONAL DESCRIPTION:
;
;	Defines the text of error messages in the fortran library (FORLIB).
;	Uses the Macro $FERR to generate error messages in propper format.
;
;	Arguments to $FERR:
;	$FERR(	1st - Warning/error character (? or %),
;		2nd - Unique three character pnuemonic for error
;			message.  A F.<3 character> symbol is created,
;		3rd - Error class number.  (21 for Forlib error messages.)
;		4th - Unique error number for message. (Not currently used.)  
;		5th - Message to appear
;
;	For more information the error message macros see FORPRM & MTHPRM.
;
; CALLING SEQUENCE:
;
;	Called from FORLIB code with a $FCALL macro (which generates):
;
;		JRST	F.nnn	;Where nnn is the 3 letter error code.
;
