Graphics Here is the BASIC program that prints the design shown on the previous pages. Notice that the data numbers in lines 80-140 are the same numbers that you see in the last illustration. Also note that the WIDTH statement in line 10 is for IBM PC BASIC; the format may be different for your system. 10 WIDTH "LPT1:",255 20 LPRINT cHR$(27)"*"CHR$(39)CHR$(42)CHR$o; 30 FOR x=1 To 126 40 READ N 50 LPRINT CHR$(N); 60 NEXT X 70 LPRINT 80 DATA 0,0,63,0,0,127,0,0,255,0,3,255,8,15,255,0~%255 90 DATA 0,127,255,0,255,255,1,255,255,3,255,255,7,255,255,15, 255,255 100 DATA 31,255,254,31,255,252,31,255,248,31,255,240,3l,255, 224,31,255,192 110 DATA 31,255,0,31,252,0,31,240,0,31,224,0,31,12~,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,l28,15,7,192,7,3,240,7,1,254,7,0,255~7~0~127~l35 140 DATA 0,31,199,0,7,231,0,1,247,0,0,255~0~0,~7,0,0~63 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 80-140 contain 126 bytes of data (42 pin columns x 3 bytes for each pin column). Lines 30-60 print the design that you see below. 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 to the inch) in both directions. 4-17

Here is the BASIC program that prints the design shown on the
previous pages. Notice that the data numbers in lines 80-140 are the
same numbers that you see in the last illustration. Also note that
the WIDTH statement in line 10 is for IBM PC BASIC; the 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 80-140 contain 126 bytes of data (42 pin columns x 3 bytes
for each pin column). Lines 30-60 print the design that you see
below.
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 to the inch) in both directions.
