;----- Overview -------------------------------------------------------------
;
; Functions provided:
;
;  cl_next

		[	:LNOT::DEF:cmdLine__dfn
		GBLL	cmdLine__dfn

; --- cl_next ---
;
; On entry:	R0 == pointer to a command line string (ctrl terminated)
;		R1 == pointer to a buffer (may be equal to R0)
;
; On exit:	CS if another word found, and
;		  R0 == updated past next word
;		  R1 preserved, buffer filled with null terminated string
;		  R2 == pointer to terminating null character
;		else CC and
;		  R0 == pointer to terminating character
;		  R1 preserved, buffer preserved
;		  R2 corrupted
;
; Use:		Extracts the next word from a command line string.  If the
;		string is in a writable buffer, you can set R1 == R0 to
;		start with.  You can build up a C-like argv array like this:
;
;			; R0 == pointer to command line in writable buffer
;
;				MOV	R1,R0
;				ADR	R3,argv
;				MOV	R4,#0
;			loop	BL	cl_next
;				MOVCC	R1,#0
;				STR	R1,[R3],#4
;				ADDCS	R4,#0
;				BCS	loop
;
;			; R0-R3 corrupted
;			; R4 == argc
;
;		This routine will handle quoted strings, considering them
;		to be single arguments.  Either type of quote will do,
;		quote doubling is required to insert quotes in quoted
;		strings.
