For instance, the following will give you all the user defined functions and variables (located in the context Global by default) In[1]:= f[x_] := x^2 In[2]:= g[x_, y_] := x^2 + y^2 In[3]:= ?Global`* Global` f g x y In[4]:= lst = Names["Global`*"] Out[4]= {"f", "g", "lst", "x", "y"} In[5]:= Definition /@ lst // TableForm Out[5]//TableForm= 2 f[x_] := x 2 2 g[x_, y_] := x + y lst = {f, g, lst, x, y} Null Null Regards, -- Jean-Marc
