[Axiom-developer] Question: local functions

[Michael Becker]

    Hi,

     
      are functions local to other functions supported in axiom input files ?

(7) -> gpp(13,1)
   Compiled code for gpp has been cleared.
   Compiling function g with type (Integer,Integer,Integer,Integer) ->
      Integer
   Compiling function gpp with type (Integer,NonNegativeInteger) ->
      Integer
   There are no library operations named gpp
      Use HyperDoc Browse or issue
                                )what op gpp
      to learn if there is any operation containing " gpp " in its
      name.

   Cannot find a definition or applicable library operation named gpp
      with argument type(s)
                                   Integer
                             NonNegativeInteger

      Perhaps you should use "@" to indicate the required return type,
      or "$" to specify which version of the function you need.
(7) -> )display val g
   Definition:
     g (x,r,m,c) ==
       if c= r
