Re: Counting the total number of available Mathematica commands ?

Hi,

the problem is that Names["*"] generate a list of all Mathematica
*symbols*
and not of all Mathematica commands. And $TopDirectory is *not* a
command and
ViewPoint will do nothing.

But global symbols have usual a associated value, functions typical not.
So probably

nlist = Names["*"];
optandfun=First /@ Select[{#, ToExpression[#]} & /@ nlist, First[#] ==
ToString[Last[#]] &]

gives the list of functions and *options*.
To remove at least the options acciciated with the funtions  we can

onlyopt = 
    ToString /@ 
        Flatten[Options[ToExpression[#]] & /@ optandfun] /. {Rule[a_,
b_] :> a,
         Verbatim[RuleDelayed][a_, b_] :> a};

and

Complement[optanfun, onlyopt]

This helps nothing for options FontFace like 
TextStyle->{FontFace->"Times"} and nothing for symbols
like Integers, Reals or Complexes that are not options
and not function definitions.

More ideas to find the *functions only* are welcome.

But I think it is impossible due to the read protection of
the build in symbols.

Regards
  Jens
