The error on the above is the missing space. However, as shown below, )abbrev ? seems really not to have documentation, but )help ? had, and is not working in this version of Axiom.

   For more information about individual commands, use the )help system
      command followed by the command name or the command name followed
      by a question mark. Some commands (such as )lisp ) may require
      the )help lisp format. For example, issue )help help or )help ?
      to find out more about the help command itself.

)help abbreviations

   If the system command or synonym abbreviations exists, help
      information is not available for it. Issue )what commands or
      )what synonyms to determine is abbreviations is a valid name.

)abbreviations ?

      information is not available for it. Issue )what commands or
      )what synonyms to determine is abbreviations is a valid name.

)help help

   If the system command or synonym help exists, help information is
      not available for it. Issue )what commands or )what synonyms to
      determine is help is a valid name.

)help ?

   If the system command or synonym help exists, help information is
      not available for it. Issue )what commands or )what synonyms to
      determine is help is a valid name.

Comparing this with the NAG version, )what commands, )help abbreviations, and )abbreviations ? behave the same, but )help help and )help ? both print out about three pages of information, including two Sections A.12. )help, and A.1. Introduction from the "on-line version of the book". So there probably wasn't any documentation on )abbreviations to begin with. But )help ? should have worked.

this is due to missing help files. In Axiom, help files are installed now, in FriCAS they are used when installed, but must be installed manually.
