Message-ID: <12242@sybase.sybase.com> Date: 5 Apr 91 21:31:00 GMT Sender: news@Sybase.COM Distribution: comp.sys.atari.8bit Organization: Sybase, Inc. Lines: 16 Folks, Anyone know how to preform bit wise operations on the Atari. I have an Atari 800xl, and have developed a simple player missle graphics game. The problem is that I have two players that fire missles, but when I move the missles up/down in memory I zap one of the players missle bit map because they share memory bytes. What I would like to do is mask out the bits that apply to a specific player. Also, all this is being done in basic, any ideas? Another question, in Atari basic how are HEX numbers represented? Thanks in advance. -- hutch
