Re: Still working on the keyboard: is this function available in Euphoria??

Isn't the keyboard buffer 32 bytes long starting at 0040:001E  (#41E)?
Or is the 32 Byte word at 0040:001E just the start position of keyb buffer?
How did you get 16 bytes long?

I would like some help on this one as I have been stuck writing keyb buffer
stuff in the past because of some confution here.
