: : What about just NULL? isn't that NATTA for any data type? or NOT_found would probably work too..
: i was wondering same thing. but would returning NULL work because you are suppose to be returning a datatype....
Given that he's expecting a very specific format for the lookup function and what it returns, and given that we have no idea what dataTypes he'll use, i don't see what we can do except assume he won't call a lookup on a nonexistent key.
