the dots as large as you see them in the example on the left in Figure

5-2. If you draw them smaller, you may have overlapping dots without realizing it.

Correct and incorrect designs

overlapping dots

dot on horizontal line

If you do accidentally overlap dots, don’t worry. The program will still work, but only one of the dots will be printed.

First definition program

Once you have drawn your dots on the grid, type in the following BASIC program and run it. If you are using Applesoft™ BASIC, see Appendix C.

100 DIM F(9)

110 FOR I=1 TO 9

120 PRINT "WHICH ROWS HAVE DOTS IN COLUMN"; 1

130 INPUT R: IF R=0 THEN 150

140F(I)=F(I)+2^(R-1)

150 IF R=0 THEN NEXT I ELSE GOTO 130

160LPRINT CHR$(27) “:“CHR$(0)CHR$(0)CHR$(0);

170LPRINT CHR$(27)"%"CHR$(1)CH$(0);

180LPRINT CHR$(27)"&"CHR$(0)CHR$(60)CHR$(60);

190LPRINT CHR$(128);
