Bit Image Sample Program
The following sample program written in BASIC produces single density bit
image graphics of the pattern shown in Figure 5–3. The 7 data bit pattern is
repeated 40 times. The printed result of running the program is shown in
Figure 5–4.
5 WIDTH “LPT1:”,255
10 LPRINT “Single Density Bit Image Graphics”
20 LPRINT CHR$(27);“K”;CHR$(24);CHR$(1);
30 FOR N=1 TO 40
40 RESTORE
50 FOR I=1 TO 7
60 READ R
70 LPRINT CHR$(R);
80 NEXT I
90 NEXT N
100 DATA 73, 146, 36, 255, 36, 146, 73
110 LPRINT
NOTE: A detailed description of the individual bit image control codes with
examples is provided in the Programming chapter.
