QUICK REFERENCE ASCII TABLE FOR THE ATARI ST COMPUTERS Version 1.1 04/05/86 By James Luczak The ASCII code is a code that represents each letter of the alphabet, both upper and lower case, keyboard symbols, such as % and *, and individual keys on the keyboard, such as the HELP key or the FUNCTION keys. ASCII stands for American national Standard Code for Information Interchange. Each letter, symbol. or key is represented by a number between 0 and 255. Since each key on the keyboard is represented by the ASCII code, you can easily check the keyboard for a particular keypress with the Basic Command X=INP(2). When Basic executes the command the program will halt, and wait for a keypress. The result of the keypress will be stored in the variable X. The number stored in X will be the ASCII code for the key or combonation of keys that were pressed. To find out what letter, symbol, or key the code stands for, refer to Appendix E of the ST Basic Sourcebook. When you get to Appendix E you start running into trouble. The ASCII table is just plain hard to read, and hard to use. It was not meant to be a quick reference chart. Like most ASCII tables, it's easiest to use if you know the ASCII code you are looking for. In most cases however, you want to find the ASCII code for a particular letter, symbol, or key. Listing 1 is an easy to use quick reference ASCII table for the Atari St series computer. The table is arranged in three columns. The NORMAL column, the CONTROL column, and the ALTERNATE column. The NORMAL column represents a SINGLE keypress. The CONTROL column represents a keypress while the CONTROL key is held down, and the ALTERNATE column represents a keypress while the ALTERNATE key is held down. Each column has three headings. The CHAR heading shows the letter, symbol, or key. The DEC heading shows the DECIMAL value of the letter, symbol, or key, and the HEX heading shows it's HEXIDECIMAL equivalent. The Quick Reference ASCII Table contains the ASCII codes for the Main Keyboard, the Cursor Control keys, the Keypad, and the Function keys. The Function Keys are labeled F1 thru F10, and SHIFT F1 thru SHIFT F10. The SHIFT Function labels represent holding the SHIFT key down while pressing a Function key. Listing 2 shows the ASCII code in numeric order.
