 Author Comment/Response m prior 09/18/07 5:18pm I'm try ing to create pure functions with variable number of arguements. First I build a list of symbols for the arguements. Then I try to use that list in the call to Function[{args},body]. However this does not seem to produce the same effect as if I manual define the arguments. In the automated method the arguments seem to remain unevaluated. Any ideas why this does not work as expected ... ? Many thanks in advance, Matt In[165]:= MakeSymbolArray[v_,size_]:= Map[Symbol[ToString[v]<>ToString[#]]&,Range[1,size]] In[166]:= sa=MakeSymbolArray[pp,2] Out[166]= {pp1,pp2} In[167]:= f=Function[sa,2^pp1 3^pp2] Out[167]= Function[sa,2^pp1 3^pp2] In[168]:= f[2,3] Out[168]= 2^pp1 3^pp2 In[169]:= f=Function[{pp1,pp2},2^pp1 3^pp2] Out[169]= Function[{pp1,pp2},2^pp1 3^pp2] In[170]:= f[2,3] Out[170]= 108 In[171]:= Map[Head,{pp1,pp2}] Map[Head,sa] Out[171]= {Symbol,Symbol} Out[172]= {Symbol,Symbol} URL: ,
