Hi

I've never thought of this a bug, just a feature of the language. Some screens
have lines > 25, and if you have set the screen to one of these modes, then you
can write to > 25. SCREEN_LINES tells you how long the screen is

SCREEN_LINES = vid_conf[VC_LINES]
SCREEN_COLS = vid_conf[VC_COLUMNS]


then just wrap position with a check for the length of the screen to prevent
crashes.

Please, any changes should not affect the abilty to write beyond 25 lines
