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.

   The index 3 is too large.

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.
