Re: List of functions ?

Thanks.  The contents of parse.inc seem to be what I want.  So far as
I can see, the first two fields will suffice.

However, this list contains more than what I want.  There are some
'non functions' at the top of the file , and some that a user doesn't
normally think of as functions, at the foot eg "ADD", "EQ" etc.  Maybe
it's possible to identify these with flag?

     There's never been a reason to export one from the expression
     parser before, so although there's a list it's not necessarily in
     the form you want.  See src/language/expressions/parse.inc in the
     build directory (it's a generated file).
     
     Quite possibly we want to generate a separate list for use by the
     GUI dialogs and export that list.
     
     Here are some considerations:
     
             * Do you want just function names, or do you want
               argument types along with them?  They're about equally
               easy to supply, as you can see from the current array.
     
             * Do you want to include unimplemented functions?  PSPP
               extension functions?
     
             * Some functions are "overloaded" in that they have
               multiple versions with the same name but different
               types or numbers of arguments; also, some functions are
               varargs.
     
             * Some functions take a optional "minimum non-missing
               arguments" argument, e.g. MAX.3(a,b,c) to only give a
               non-missing result if all of a, b, and c are
               non-missing.
