***** Begin Revision History *****

30	-----	-----	MAKE DOTTEDNAMES A GLOBAL SO THAT EXPRES CAN ACCESS
			IT TO RESOLVE LIBRARY FUNCTION ACTUAL PARAMETERS

			DO NOT ALLOW TYPED FUNCTION NAMES TO BE GENERIC.

31	312	16668	FOR THE VARIABLE NUMBER OF ARGUMENTS FUNCTIONS,
			CHECK TO MAKE SURE THAT THERE ARE AT LEAST 2., (JNT)

***** Begin Version 5A *****

32	563	22541	GIVE CORRECT ERROR MESSAGES FOR BAD ARGUMENT
			TYPES TO LIBRARY ROUTINES., (DCE)
***** Begin Version 6 *****

33	761	TFV	1-Mar-80	-----
	Add dotted names of new library routines into tables.
	Choose name based on /GFLOATING

34	1004	TFV	1-Jul-80	------
	Only choose gdottednames for DP functions
				
35	1075	EGM	28-May-81	--------
	Add GFL equivalents to IDINT (IGINT) and SNGL (GSNGL).

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

36	1241	CDM	29-Jul-81		----
	Add intrinsic functions (ANINT, DDIM, DINT, DNINT, DPROD, IDNINT,
	NINT) and their G-Floating counterparts (GDIM, GINT, GNINT, GPROD,
	IGNINT) and change MAKLIBFN to always look in the GDOTTEDNAMES
	table whenever /GFL is specified.

37	1252	CDM	10-Aug-81
	Add names for inline generic functions for which 77-standard gives
	no specific names.  Also change MAKLIBFN so that when it finds CMPLX
	called with only 1 argument, it changes the function name to CMP1.R,
	since CMPLX may now have 1 or 2 arguments.

40	1264	CDM	25-Sept-81
	Add CMPL.C, MAX, MIN, LOG10, CHAR, ICHAR, INDEX, LEN, LGE, LGT,
	LLE, LLT, NOP's to function tables.
	In MAKLIBFN, make character data arguments illegal for generic
	functions.

41	1270	CDM	6-Oct-81
	Changes to MAKLIBFN;
	-Added one more argument to the call,
	-Added error for octal and literal argments to non-specific generic
		function,
	-Added warning for declaration of function to something other
		than the value found in LIBATTRIBUTES.

42	1275	CDM	20-Oct-81
	Added code to MAKLIBFN to check if a function with no (or less)
	arguments is called.  SIN() is illegal for a library function!

43	1434	CDM	14-Dec-81
	Add length for character library functions (CHAR in particular).

44	1436	SRM	16-Dec-81
	Set CHARUSED if call an intrinsic function that takes a character
	arg or returns a character value

1505	AHM	12-Mar-82
	Make MAKELIBFN set the psect index of symbol table entries for
	dotted function names to .CODE.

1513	RVM	22-Mar-82
	Take the code that forms the symbol table entry for the dotted
	names of library functions out of MAKLIBFN and make it into a
	new global routine MAKDOTTEDNAME.  Also, have MAKDOTTEDNAME set
	INEXTERN for the dotted name if the undotted name has INEXTERN
	set.  (HSCHD in OUTMOD uses INEXTERN to determine if a descriptor
	needs to be created for a character routine.)  Also set the global
	flag CHDECL if MAKDOTTEDNAME sees a intrinsic character.  CHDECL
	is used to signal that HSCHD needs to be called at all!

1543	RVM	25-May-82
	Under /GFLOATING, the function CMPL.G should be used to convert
	two DOUBLE PRECISION numbers to COMPLEX.

1535	CDM	1-June-82
	Error message for ICHAR with character constant of length > 1.

1551	AHM	4-Jun-82
	Remove edit 1505  because external references  no longer  have
	their psect index set.

1567	CDM	24-Jun-82
	Set IDFNFOLD in symbol table if function could be folded into
	a constant.


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

2301	RVM	28-Jan-84
	Make the compiler know about the MIL SPEC/VAX FORTRAN bit
	manipulation functions.  They are new INTRINSIC functions.

***** End V10 Development *****
