There is a RAM location around $05xx (*) that stores the last pattern of SHIFT, CTRL, CBM but it seems not to work under BASIC. Any tip? S\_/S (*) Sorry for not complete info, but I'm at job place, and I haven't +4 docs here Posted By Gaia on 2008-03-27 11:07:12  Re: Shiftkey detecting I always used $C6 and $0543. Something like: 10 PRINTPEEK(DEC("C6")),PEEK(DEC("543")) 20 RUN Posted By JamesC on 2008-03-27 17:20:22  Re: Shiftkey detecting PEEK(1347) is what you seek: 0 for no control keys 1 for Shift (either left or right) 2 for Commodore key 4 for Control key The key has to be pressed when the PEEK is evaluated, for it to be seen this way.
