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. 10 WIDTH "LPT1:",255 20 LPRINT CHR$(27)"*"CHR$(39)CHR$(42)CHR$(0); 30 FOR X=1 To 126 40 READ N 50 LPRINT CHR$(N); 60 NEXT X 70 LPRINT 80 DATA 0,0,63,0,0,127,0,0,255,0,3,255,0,15,255,0,31,255 90 DATA 0,127,255,0,255,255,1,255,255,255,3,255,255,7,255,255,15, 255,255 100 DATA 31,255,254,31,255,252,31,255,248,31,255,240,31,255, 224,31,255,192 110 DATA 31,255,0,31,252,8,31,240,0,31,224,0,31,128,0,31,240,0 120 DATA 31,255,192,28,255,224,28,127,240,28,15,248,30,0,252, 31,0,126 130 DATA 15,128,15,7,192,7,3,240,7,1,254,7,0,255,7,0,127,135 140 DATA 0,31,199,0,7,231,0,1,247,0,0,255,0,0,127,0,0,63 In this program, line 20 assigns the graphics option (24-pin tripledensity) 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. 4-16 Software and Graphics

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.
