no space after the 0 and then press RETURN. The next prompt on the

screen is:

ENTER A MASTER PRINT MODE NUMBER

For now, enter a 24. Remember, all codes from 0 to 255 produce a

combination of print modes, but there are only 16 unique combina-

tions. You may want to refer to Figure

5-2

for the other possibilities.

Figure 16-4. Giant G

The four characters defined in lines 270 to 300 combine to print a giant

G. The 0 is printed as four small characters. Figure 16-4 illustrates the

way the program arranges the four versions of each character to make

a larger letter.

Line 140 examines the A$ string, character by character, and deter-

mines its ASCII value. Line 150 prints what’s now stored in the loca-

tions for the Roman upper- and lowercase versions of each character

on the first pass of the print head. On the second pass, Y is set to 1 and

128 is added to A in line 140. Thus line 150 then prints what has

replaced the Italic versions of the character.

To get a better idea of what this program can do, you’ll need to add

more data. The DATA lines below supply data for the letters A-M-E-S

and for the space character. (It is necessary to redefine the space char-

acter since two of its four components print as @ signs.)

Be careful. Although the space character is user-definable, you

should avoid using it as anything other than a space character. No

matter how it is defined, the space character will never print at the

beginning or end of a line.

Enter the data lines as shown in Figure 16-5. Now add a loop to

READ the new data by changing these lines:

FOR W=1 TO

READ L: PRINT CHR$(L)

NEXT Z: NEXT Y: NEXT W
