Below is the BASIC program that prints the design shown on the
previous pages. Note that the data numbers in lines 80 through 140 are
the same numbers that are at the bottom of each section in the last
illustration. The WIDTH statement in line 10 is for IBM PC BASIC; the
WIDTH statement format may be different for your system.

In this program, line 20 assigns the graphics option (24-pin
triple-density) with code 39. Code 42 sets the number of pin columns at
42. Lines 80 through 140 contain 126 bytes of data (42-pin columns x 3
bytes) for each pin column. Lines 30 through 60 print the design that
you see below:
