#include "ti82.h"

.org 0
.db "Disp. ROM Ver.",0

	ld HL, (ROM_VERS)
	ld A, (HL)
	ROM_CALL(M_CHARPUT)	; display %A on screen, menu style

	I receive an 8 on my screen when this program is run and my
version # is 18. Let me know if this works for other ROM
versions....anyone. =) Thanks.

	Oh! I forgot to tell you to add the following line to the TI82.H
file.

	ROM_VERS	=$8C3E	; ROM version byte
