Clock.bas is simple to use, just enter the number of seconds you want the clock to run. This is needed because there is no way to end the macro by a keypress or mouse click. Originally written in QuickBASIC in 1991, many of the formulas are almost exactly the same and some of the LINE commands only needed minor changes. Many types of animation can be programmed including one I have been working on that simulates a G-Code Program.
