So how do you count from decimal-0 to decimal-3 using the binary pushbuttons? The
two-bit binary equivalent of decimal-0 is 00. When you don’t press either of the
pushbuttons, the decimal output is 0 in the Debug Terminal. When you press the right
button, you get 01, which has a decimal equivalent of 1. When you press the left button,
you get 10, which has a decimal equivalent of 2. When you press both pushbuttons, you
get 11, which has a decimal equivalent of 3.
About the Code
As with the program of the previous chapter, the first lines start with an apostrophe, so
they are comments and compiler directives, and the BASIC Stamp ignores them.
