I'm using Axiom 3.9 and when I execute inverseLaplace I got a result in function of %%A0 but Axiom dosn't say what %%A0 is. In gmane.comp.mathematics.axiom.general tell me that it could be a bug not reporting what the temporaru symbol %%A0 is. Example:

(1) -> F(s) == (s**2 - 9*s - 32)/(2*s**3 - 3*s + 4)

inverseLaplace(F(s),s,x)

   There are no library operations named ** 
      Use HyperDoc Browse or issue
                                 )what op **
      to learn if there is any operation containing " ** " in its name.
   Cannot find a definition or applicable library operation named ** 
      with argument type(s) 
                                 Variable(s)
                               PositiveInteger

      Perhaps you should use "@" to indicate the required return type, 
      or "$" to specify which version of the function you need.
   FriCAS will attempt to step through and interpret the code.
