Not sure, but would this alternative using a dispatch table work? data = Table[{j, "x" ~~ ToString[j] }, { j,1,10000 }]; dict = Dispatch[Rule@@@data]; ReplaceAll[13, dict] x13 ReplaceAll[995, dict] x995 = = = = = = = = = = HTH :>) Dana DeLouis Mac & Math 8 = = = = = = = = = = On Mar 14, 1:46 am, JasonE <ebaughja... at gmail.com> wrote: > Hello folks, > > How can I make a sequence that includes lists? > Ex: > Sequence[apple, {rock, tree), {ocean, lake}] > > Here is my specific problem: > > I use this function to make associative arrays: > IndexedVariable[var_,indicesValues__]:=With[{dict=List[indicesValues]},Scan [(var[#[[1]]]=#[[2]])&,dict]] > > (I got it from:http://www.physic.ut.ee/~kkannike/english/prog/mathematica/index.html...) > > Here is an example of how it takes arguments: > IndexedVariable[f, {1, "a"}, {2, "b"}, {3, "c"}] > > In[2]:= f[1] > Out[2]= a > > In[3]:= f[2] > Out[3]= b > ect... > > You can imagine, some associations are too long to type out by hand. > Ex: {1, x1}, {2, x2}...{1000, x1000} > > When I make these associations programtically, I get a list back: > {{1, x1}, {2, x2},...{1000, x1000}} > > IndexedVariable[f,{{1, x1}, {2, x2}, {3, x3}...{1000, x1000}}] > does not work. > > It wants a sequence. > > How can I make a sequence that includes lists? > > Thanks, > Jason > > Jason Ebaugh > Contact: jasoneba... at jasonebaugh.info > LinkedIn:www.linkedin.com/in/jasonebaugh
