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 (24pin
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
