nBlock graphics characters and special symbols

Besides the upper and lower case letters and symbols that we are by now familiar with, your printer has a whole different set of characters that are for special uses. These characters include block graphics for drawing forms and graphs, and special sym- bols for mathematical, engineering and professional uses. The special characters are included in two character sets. The character set you normally use with IBM mode is called character set #l. The special characters are printed out when you send ASCII codes 160-255 to the printer.

Your printer also offers character set #2 which is almost the same as character set #l except for the addition of ASCII codes 3-6,21, and 128-159. Character set #2 is selected with (ESC) “6”; to go back to character set #l, use (ESC)“7”.

You can also specify the power-on default character set by set- ting DIP switch l-7 on for character set #l and off for character set #2. The following program will print out all of the graphics characters available:

10LPRINT CHR$(27);"0";

20LPRINT CHR$(27);"6";

30FOR J=3 TO 6

40LPRINT " d';J;CHR$(J.);CHR$(9);
