Subscript[x, y] and the Symbol x

Dear Mathgroup: The Subscript function in Mathematica has no built-in meaning. What definition can I give this function to allow me to use Subscript[x,y] as a "stand-alone" symbol that is completely distinct from the Symbol x or the Symbol y? For example: In[1]:= \!\(f[x_, y_] := x\_y\ + \ x + y\) In[2]:= f[2,2]//FullForm Out[2]//FullForm= Plus[4,Subscript[2,2]] This is exactly what I don't want. Instead I want Plus[4,Subscript[x,y]]. Is there a way to do this? Thanks for your help. -- Curt Fischer Tokyo Institute of Technology Dept. of Bioengineering
