Plotting a Bit Image Pattern
You can produce a a bit image pattern in four steps:
1. Lay out the graphic(s) pattern you want to print, on a quadrille pad or
graph paper.
2. Determine the decimal equivalent of each bit image data byte required
to produce your pattern (Figure 5–3).
3. Write a program to generate the complete pattern.
4. Enter and run the program on the host computer.
