What version?

fricas
(1) -> )version

"FriCAS 1.3.12 compiled at Sat  7 Jun 23:54:49 CEST 2025"

New domain Domain:

fricas
)show Domain

   The )show system command is used to display information about types 
      or partial types. For example, )show Integer will show 
      information about Integer .

      Domain is not the name of a known type constructor. If you want 
      to see information about any operations named Domain , issue
                         )display operations Domain

For example:

fricas
LD:=[Integer,Float,String]

 LISP output:
(UNPRINTABLE UNPRINTABLE UNPRINTABLE)
Type: List(Type)

New domain Syntax:

fricas
)show Syntax

   The )show system command is used to display information about types 
      or partial types. For example, )show Integer will show 
      information about Integer .

      Syntax is not the name of a known type constructor. If you want 
      to see information about any operations named Syntax , issue
                         )display operations Syntax

fricas
reify(String)

   There are no library operations named reify 
      Use HyperDoc Browse or issue
                               )what op reify
      to learn if there is any operation containing " reify " in its 
      name.

   Cannot find a definition or applicable library operation named reify
      with argument type(s) 
                                    Type

      Perhaps you should use "@" to indicate the required return type, 
      or "$" to specify which version of the function you need.

That bug has been corrected in recent versions of OpenAxiom?. Any chance for update?

Humm, this version of OpenAxiom? seems a bit old. Any change of upgrade to more recent ones?

OpenAxiom? now displays InputForms? --Bill Page, Thu, 16 Oct 2008 18:54:56 -0700 reply
in infix (or m-expression like) notation like this:
fricas
phi := operator phi

   There are 2 exposed and 10 unexposed library operations named 
      operator having 1 argument(s) but none was determined to be 
      applicable. Use HyperDoc Browse, or issue
                            )display op operator
      to learn more about the available operations. Perhaps 
      package-calling the operation or using coercions on the arguments
      will allow you to apply the operation.

   Cannot find a definition or applicable library operation named 
      operator with argument type(s) 
                                BasicOperator

      Perhaps you should use "@" to indicate the required return type, 
      or "$" to specify which version of the function you need.
