  12. I sure hope they figure out the reason for the following oddity:
  13.  
  14. In[1]:= $Version
  15.  
  16. Out[1]= SPARC 2.0 (August 26, 1991)
  17.  
  18. In[2]:= Table[Limit[Exp[x]/x^n,x->Infinity],{n,4}]
  19.  
  20.                                               x
  21.                                              E
  22. Out[2]= {Infinity, Infinity, Infinity, Limit[--, x -> Infinity]}
  23.                                               4
  24.                                              x
  25.  
  26. A recent article in sci.math indicates that Maple has a similar
  27. problem.  You can never trust computer programs too far.
