Depending on context it is a function of at least three arguments (independent variable, the "limit", and a function) and may well a) not even have a value and b) even if it does, it may not be in the range of the function argument. Actually, in mathematical parlence "lim" is not even an operator. /Jon -- Jon Anthony Organon Motives, Inc. Belmont, MA 02178 617.484.3383 jsa@organon.com
