You need to use the Notation package to Symbolize your function. Copy the Cell Expressions below into a Mathematica notebook, and evaluate to see the required result. I have included full cell expressions so you can see what is going on more clearly. CAVEAT: when you use Symbolize (and other functions in the Notation package) you should enter it using the Notation palette that appears when you execute <<Utilities`Notation`, rather than entering it manually. This is because there is some hidden tagbox information that is generated. { Cell[BoxData[ RowBox[{"<<", "Utilities`Notation`"}]], "Input", CellLabel->"In[1]:="], Cell[BoxData[ RowBox[{"Symbolize", "[", TagBox[ SubscriptBox["f", "1"], NotationBoxTag, TagStyle->"NotationTemplateStyle"], "]"}]], "Input", CellLabel->"In[2]:="], Cell[BoxData[ RowBox[{ RowBox[{ SubscriptBox["f", "1"], "[", "x_", "]"}], ":=", RowBox[{"x", "^", "2"}]}]], "Input", CellLabel->"In[4]:="], Cell[BoxData[ RowBox[{"?", SubscriptBox["f", "1"]}]], "Input", CellLabel->"In[5]:="] } Steve Luttrell <seb at magda.ifj.edu.pl> wrote in message news:cq8tj5$h18$1 at smc.vnet.net... > when I define a function with a subscript in its > name: (cell content below) > > In[1]:= \!\(f\_1[x_] := x^2\) > > I can't see it by use of information operator: > > In[2]:= \!\(\(?\ f\_1\)\) > > Information::ssym > > Out[2]:= \!\(Information[f\_1, LongForm -> False]\) > > of course I may ask: > > In[3]:= ?
