ASCII table
Development systems
As not every key on the Atari keyboard is assigned an ASCII-code, it is necessary in a few cases to interrogate the relevant scancode directly. Normally however this should be necessary only for the 'special' non-print keys such as the cursor and function keys.
The following table gives an overview of the important scancodes for German, UK and North American keyboards as well as the standard VDI code. Keyboards for other countries/languages may differ for some keys (see NKCC below).
Where two characters are shown for a non-letter entry, the second is the upper character marked on the key - i.e. produced with one of the [Shift] keys pressed; the scancode remains the same.

Note: A small problem is the contry/language-dependent evaluation of the scancodes, since after all programs ought to work correctly abroad as well. Here one can recommend the Normalized Key Code Converter (NKCC) by Harald Siegmund, which solves just this problem.
