    Jack,

    ·· If your buttons are connected to a group of pins on the same port, you could use INA, for example, to read 4 pins at once.· Then you could compare that to a number.· For example, if you had switches connected to P0 and P1, you could use:

    IF INA = %0011 THEN Start_Countdown

    ·· BTW, you should post the version of the book you're·using when asking questions, since different revisions have things on different pages.
