; --- bTalk_lvblnk ---
;
; On entry:	R0 == pointer to variable name to find (not tokenised)
;
; On exit:	R0 == address of lvalue
;		R1 == type of lvalue
;
; Use:		Tries to locate the given BASIC variable.

		IMPORT	bTalk_lvblnk

; --- bTalk_create ---
;
; On entry:	R0 == pointer to name of variable
;
; On exit:	R0 == address of variable lvalue
;		R1 == type of variable created
;
; Use:		Creates a variable, if it doesn't already exist.  Otherwise
;		a pointer to the existing variable is returned.

		IMPORT	bTalk_create

; --- bTalk_store ---
;
; On entry:	R0 == lvalue in which to store
;		R1 == type of lvalue
;		R2 == (integer) value to store
;
; On exit:	--
;
; Use:		Stores an integer value in a BASIC variable.  The value is
;		converted to floating point if required (without loss of
;		precision).

		IMPORT	bTalk_store

; --- bTalk_load ---
;
; On entry:	R0 == address of lvalue
;		R1 == type of lvalue
;
; On exit:	R2 == integer value of lvalue
;
; Use:		Loads an integer variable from an lvalue.

		IMPORT	bTalk_load

; --- bTalk_eval ---
;
; On entry:	R1 == pointer to a control-terminated string
;
; On exit:	R0 == value of expression
;
; Use:		Evaluates a BASIC expression.

		IMPORT	bTalk_eval

; --- bTalk_match ---
;
; On entry:	R1 == ctrl terminated string
;		R2 == destination pointer
;
; On exit:	--
;
; Use:		Tokenises the given sting, and puts the result in the
;		destination buffer given.

		IMPORT	bTalk_match
