Large Letters: Double High Let's stack two characters, one on top of the other, with these changes: 10 LPRINT CHR$(27)"1"CHR$(27)"U1"; 100 LPRINT "A" 110 LPRINT "B" 200 210 DDAATTAA 16,32,95,0,64,0,127,0,63,0,0 14,0,123,0,3,0,123,0,1,127,0,15 Line 10 changes the lines spacing to 7-dot and turns on Unidirectional Mode for precise alignment of the two lines. If there are slight gaps between rows, change the line spacing to 6-2/3-dot with CHR$(27)"3"CHR$(20). With a little imagination, you can create some dynamite patterns by combining characters. Giant Letters: Double High and Double Wide For even larger type styles, you can design letters that are both two characters tall and two characters wide. This gives you an 18 by 22 matrix. If you have a 7-bit system, you will have to skip to "Core Sets," below. Which ASCII numbers can be use to store the four characters that will make up each letter? A quick glance at the ASCII chart (Appendix A) shows that there are four symbols that readily relate to each letter of the alphabet. They are the upper- and lowercase versions of each letter in its Roman and Italic typefaces. For example, the letter G could be designed using the following four ASCII codes: CHR$(71) Uppercase Roman G CHR$(103) Lowercase Roman g CHR$(199) Uppercase Italic G CHR$(231) Lowercase Italic g Such usage is shown in Figure 16-2. 217
