While using Mathematica v3.0 on Windows 95, I am unable  to delete a
function that I have defined with a subscript. I have defined A_n[x_]
:= 2 x, where _n is subscript n or [ctl]_n.  Using Clear[A_n] or A_n =.
does not work. A copy of the session  is shown below.  Any suggestions?

Thanks, .... Al Larson
