This is done by setting the seventh bit (adding 128). There are other codes used which are outside this range: ATASCII Function 155 End Of Line (Return) 156 Delete line 157 Insert line 158 CTRL-Tab 159 Shift-Tab 253 CTRL-2 (buzzer) 254 Delete character 255 Insert character See your Atari Reference Manual, pages C1 to C3 and F1. In order to print the arrow keys, clear, insert, delete, buzzer, escape key, or any of the codes listed above to the screen, you must press the ESC key before entering the keyboard character(s). Not all of these codes can be sent to the printer. ATASCII codes zero to 31 print blank or they may send control codes to your printer, depending on the make. 96 will print a backwards apostrophe instead of a diamond, 123 will print a left bracket instead of a spade, 125 will print a right bracket instead of a clear, 126 will print a tildis instead of a backspace and 127 will print a blank instead of tab. There is a third set of codes used by the Atari keyboard handler. These values are listed in the OS User's Manual.
