Chapter 5
Wow! A jackpot. Using the bottom of an old Coke bottle as a magnifier, we see that each column is 7 dots high. 50 columns of 7 rows of dots. The sum of the bottom 7 pin numbers is
1 + 2 + 4 + 8 + 16 + 32 + 64 = 127
So that’s how they do it!
Quiz TimeQuestion: What single number will allow us to fire only the pins labeled 1, 4, and 16? Think it through now. How about . . .
1 + 4 + 1 6 = 2 1 ?
Let’s try
30 PRINT CHR$ (21);
and RUN.
Oh - winning is so much fun!
Don’t be too concerned about what movie is playing on your video screen. It may not know how to handle these codes. It’s what’s happening on the printer that counts.
The Grand SchemeThis is starting to make sense. The “logic” pattern must be:
