;	Attempt to handle remote directory filespecs a bit better.  If the
;	spec being parsed is coming from a DAP name message, instead of 
;	doing the usual PPN/alphanumeric directory test, assume that it is
;	a numeric directory.  This solves NFT's problem where it blew up
;	trying to deal with directories like [000000] or <7-EMACS>.
;	Invent a new entry point for .FILSP, called .FILSC, which will 
;	always treat directories as names.  Change .DPRNN so that it will
;	call the alternate entry point.

;.PNMNW -- INPUT TELEPHONE NUMBER
;.PNMNC -- DITTO FIRST CHARACTER IN C
;
;A "TELEPHONE" NUMBER IS DEFINED AS:
;
;	[[<PCHAR>]] [ "(" <DCHAR><DCHAR><DCHAR> ")"] [[PCHAR]]
;
;	<DCHAR> ::= "1", "2", "3", "4", "5", "6", "7", "8", "9", "0", -
;			 "*", "#"
;	<PCHAR> ::= ".", "-", "X", <DCHAR>
;
;THE "*" AND "#" DIGITS EQUATE TO TOUCHTONE KEYS OF SAME GRAPHIC
;THE "." DIGIT INDICATES A 5-SECOND PAUSE IN THE DIALING SEQUENCE;
;THE "-" AND "X" CHARACTERS ARE NOISE CHARACTERS ALLOWED SIMPLY BECAUSE
;PHONE NUMBERS OFTEN CONTAIN THEM - A MAXIMUM OF ONE EACH IS ALLOWED.
;
;THE ENTIRE PHONE NUMBER MAY BE ENCLOSED IN DOUBLE-QUOTES (THIS IS THE
;ONLY WAY TO HAVE A LEADING "AREA CODE"). THE PHONE NUMBER SCAN WILL
;NORMALLY BE TERMINATED BY A SPACE - IF ENCLOSED IN QUOTES THEN SPACES
;ARE SIMPLY IGNORED.
;
;EXAMPLES:
;
;	1234			;SMALL NUMBER, PROBABLY AN IN-HOUSE EXTENSION
;	X1234			;SAME THING
;	123-4567		;NORMAL 7-DIGIT LOCAL PHONE NUMBER
;	1234567890		;NORMAL 10-DIGIT LONG DISTANCE NUMBER
;	"(123) 456-7890"	;NORMAL 10-DIGIT LONG DISTANCE NUMBER
;	9.1234567		;"9", PAUSE, 7-DIGIT LOCAL PHONE NUMBER
;	9.(123)456-7890		;"9", PAUSE, 10-DIGIT LONG DISTANCE NUMBER
;	"9. (123) 456-7890"	;"9", PAUSE, 10-DIGIT LONG DISTANCE NUMBER

;TYI--COROUTINE TO HANDLE SPECIAL BLANK COMPRESSION,

;THE TRICK IS TO :
;  1-COMPRESS MULTIPLE SPACES
;  2-IGNORE LEADING SPACES ON EACH LINE
;  3-IGNORE TRAILING SPACES ON EACH LINE
;  4-IGNORE COMMENTS ON EACH LINE (;FOO)
;  5-IGNORE LINE FEEDS PRECEEDED BY HYPHEN (CONTINUATION)
;

;	RH CONTAINS THE LAST CHARACTER IN SOME CASES
;THE COROUTINE PC IS IN SCANPC
;	THIS IS 0 UNTIL A NON-SPACE IS SEEN IN A LINE
;	IT IS RESET TO 0 AT THE TOP LEVEL
;BY CONVENTION, T1 IS USED FOR CALLS AND IS PRESERVED ACROSS
