From what I see, after I restructured the code to get rid of the GOTOs, you might want to move the _KEYCLEAR however.

Code: (Select All)

Print "hit a key"
Do
    _KeyClear '                              clear the buffer before looking for any new keystrokes
    Do
        _Limit 30 '                          limit resource usage
        k = _KeyHit '                        get code of key press
        Locate 12, 40: Print k; Space$(5) '  erase previous key code
    Loop Until k > 0 '                      if there are no keys pressed, have another look - but only do this max 30 times per second
    Locate 13, 1: Print Space$(13); '        erase previous key code announcement
    Locate 13, 1: Print "ok, saw"; k '      announce key that was recognized
Loop Until k = 27 '                          look for another key press (exit with ESC)

For this short of an example, I'd think the above is what you want.  Just ask yourself, "Do I want to process current key hits, or hits off the keyboard buffer?"  Here, it appears you're just wanting to print the code for current key hits -- thus the _KEYCLEAR before the _KEYHIT loop.  If you're wanting to check the whole buffer and process it however, you'd probably want that _KEYCLEAR outside the main loop completely, and between the PRINT and the DO statement in the code above.
