KEY PRESSED

The KEY PRESSED command allows you to know the pressing state of a single specific key, during the "duty cycle" of the keyboard driver. The reading is deferred: therefore, it is possible to detect the pressing of just one key at a time but there is no possibility that the pressing of the key is not detected.

The parameter of this function is the so-called "keycode". Each key on the target computer's keyboard is encoded by a value, which is specific to the hardware being considered. It should not be confused with the ASCII code, which is a representation shared between the various targets.

All the keys on the keyboard have been encoded by a specific constant, which is part of the dictionary of this language.
