Just curious,,doesn't _Keyhit use the same key press repeat delay that Inkey$ uses?

So, why use this in place of k=ucase$(inkey$)? Apart from the cool looking code.

Basic answer:  numbers are faster than strings.  

k isn't = ucase$(inkey$) as you assert above.

You'd need k = ASC(ucase$(inkey$)) to come close to the right answer.  (I say CLOSE, because it doesn't deal with extended inkey$ values, such as the arrow keys.)

A true equivalent would be:  

Code: (Select All)

Do
    k = _KeyHit
    i$ = InKey$
    If i$ <> "" Then
        If Len(i$) = 1 Then i$ = i$ + Chr$(0)
        k1 = CVI(i$)
    Else
        k1 = 0
    End If
    If k Then Print k, k1
    _Limit 30
Loop Until k = 27

If you run the above, you'll see there's STILL a difference between the _keyhit value and what we've translated for our inkey$ value -- _KEYHIT can give us both an UP and DOWN code, while INKEY$ just tells us when a key is pressed DOWN.  

^ And that's the differences in the two in a nutshell.
