- Character codes
-
-
-
- To find out a character's character code either look up the character
- in the table given in the back of your User Guide, or press the Calc
- button and type the "%" sign followed by the character
- for example "%P" returns 80. Characters with codes from 0 to 127
- are the same as in the ASCII character set. Codes 128 to 255
- are compatible with the IBM code page 850.
-
- Codes from 256 upwards are for other Series 3a keys see
- the list below.
-
- *** Character codes of special keys
-
- The GET and KEY functions return the character code
- of the key that was pressed. Some of the keys are not in the character
- set. They return these numbers:
-
- Esc 27 Tab 9
- Delete 8 Enter 13
-
-
- Special keys
- " UP " 256 " DOWN " 257
- " RIGHT " 258 " LEFT " 259
- Pg Up 260 Pg Dn 261
- Home 262 End 263
- Menu 290 Help 291
- DIAMOND 292
-
- The Psion key adds 512 to the value of the key pressed. For example,
- Psion-a is 609 (512+97), and Psion-Help (Dial) is 803 (512+291).
-
- *** Special character codes with PRINT
-
- These values can be used with PRINT and CHR$():
- 7 beep
- 8 backspace
- 9 tab
- 10 line feed
- 12 form feed (clear screen)
- 13 carriage return (cursor to left of window)
-
- For example, "PRINT CHR$(8)" moves the cursor backwards, one
- character to the left.
