>Trey and Larry have already given you the answer. I, however, would strongly recommend against doing something like this. Basically, from what I understand, it'll break down functional cohesion. IOW, while the program may be doing two similar things, they won't be the same. This can cause you a great deal of problems later on.

Just an observation here (basically I agree with your view), but isn't this just a "roll-your-own" form of object oriented programming - you use the same function, but the effect is different based on the caller ? In normal OO programming, the detail of how the different function (method) is called is usually hidden, in this case it's done manually.
