Nonexistent limits

I wa trying to find some limits in Mma (v2.03) on a Mac:

In[1]:=
  <<Calculus`Limit`

In[2]:=
  Limit[ Abs[x]/x,x->0]

Out[2]:=
  0

Now, this function does not have a limit (I can supply a proof if you like).
Is there a way that I can modify Mma's limit function so that it will find
some of the functions that do not have limits?
