; HISTORY
;  2011-06-12 : [jDG] Creation
;
; Text definitions (text_french.asm example):
;	TCODE	tYes,	"Oui"					; Yes
;	TCODE	tNo,	"Non"					; No
;	TCODE	tLogbk,	"Carnet de plongées"	; Logbook
;
; Text direct usage:
;	lfsr	FSR1,tYes						; load a 12 bit text index
;	call	strcpy_text						; copy to string buffer
;	PUTC	'/'								; place a single character into the text buffer
;	lfsr	FSR1,tNo
;	call	strcat_text_print				; append next text and call word processor to output all text to the screen
;
; RATIONALS:
;  - The macro should define a label so that text files can be reordered
;    to keep consistency while adding more options (and make translator life easier).
;
;  - The text positions is keept in menu blocks for the menu processor.
;
;  - library function take text number from the FSR1 register, because a
;    lfsr instruction loads a 12 bit constant at once.

; strcpy_text : copy a multiling text into string buffer

; Input  : FSR1    text index

; strcpy_text_print : same as above, but calls word processor afterward
