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.

140 DATA
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 following
design:
Notice that the dots overlap quite a bit. This design was printed
using the triple-density 24-pin graphics option because the density
is the same (180 dots per inch) in both directions.
