   = KEY STATE(keycode)

The KEY STATE command allows you to know the pressing state of a single specific key. The reading is immediate: therefore, it is possible to detect the pressing of even more than one key at a time and, if the user is too fast or the program is too slow, there is the 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.

  IF KEY STATE(KEY A) THEN
      PRINT "A has been pressed!"
  ENDIF
