Hi John You could use contexts: Define a new context "Efficient`" and put it in front of "System`" in the context search path. Then you can define your own "Transpose" etc inside this context and use the built-in "Transpose" by fully qualifying it (System`Transpose) in the implementation of your "Transpose". Here's an example how this can be done in the context "Global`": In[1]:= Global`Transpose[x_]:= System`Transpose[x] + a In[2]:= Transpose[{{c,d,e}}] Out[2]:= {{a+c},{a+d},{a+e}} Yours sincerely Bruno
