I am not sure if I understand your post completely. Do you mean that you enter just one word for hal and then it malfunctions? As I wrote before and it has been written about for several years now, Hal does not understand or normally respond to one-word-sentences, which is of course ia an oxymoron as sentences need a subject and a predicate normally, not counting yes or no type answers. People tend to forget that Hal disects your input and then trys to find the proper reply to what you have said. It can not make heads or tails out of one word replys and thus will either malfunction or not function at all.
