In the program below, we’ve taken the logo graphics informa- tion and put it into BASIC DATA statements. The program itself is short and simple. The loop starting at line 100 reads the data statements into a string array variable called LOGO$. In line 170 we change the line spacing to 8/72 inch so that the lines of graphics data will connect vertically. The actual printing is done in the loop between lines 180 and 210; line 190 sends the graphics control code to the printer and line 200 sends one line of graphics data.
The printout from the program is shown right below the pro- gram.
