After thinking some more, typing stuff will obviously enter stuff in video/screen ram. Did a bit of testing. BASIC seems to ignore reverse / non reverse mode. So by typing "<home>" and cursor left three times, space, cursor right one time, and shift+y, it would be possible to execute a SYS. BINGO! This assumes that my trick will actually work. Without that there is no shift and there is no clr/home key. Also there is no 1 or 2 and no plus/minus/multiply/divide chars, and without shift it's impossible to call functions (to do some kind of trick like to get a function to return some address in screen ram). -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
