Yes, I always speak of « my » version of Axiom, sorry. GCL is buggy on
my system. I have absolutely no idea why. I tried hard to debug this for
other GLC users (and Camm) without success :-( GCL is a complex piece of
software for me...

Here is its manifestation:

   You have two options. Enter:
     top        to return to top level, or
     break      to enter a LISP break loop.

   Please enter your choice now:

The 'continue' choice is missing !!! I can't use GCL with this bug. The
funny thing is that I have used Axiom for maybe 2 years without noticing
this. 

So actually I'm using a mix of Axiom/FriCAS/OpenAxiom that builds/runs
on CMUCL, SBCL and Clisp. It's simpler to perform experimentations. I
plan to completely switch to FriCAS, I just want memory usage in it :


(2) -> 1/2

        1
   (2)  -
        2
                   Type: Fraction Integer
                   Time: 0.002 (EV) + 0.004 (OT) = 0.01 sec
                   Storage: 96K (EV) + 28K (OT) = 124K bytes

I will drop a patch on the FriCAS mailing list when time will permits.
It will eventually be included in. In the past I had several
experimental Axiom trees but stopped to "maintains" them because of lack
of time (I have lost a tree that save/restore the complete environnement
when starting/quitting Axiom, grrrr!!!!). Theses trees were generally
pure experimentation and not interesting in themselves.

Actually I do not use CAS a lot (just for simple computations).

Hope to be better understood.
