Hi Lispers,
does somebody have information on a dialect of lisp called SLISP
(Standard LISP)? Is it comparable to CL?
Does anybody still use it?
I saw that there is a computer algebra system called sheep for slisp.

Anybody any experience?
groetjes,
Marc

Standard Lisp was (I think) an attempt to standardise a lisp on which
computer algebra systems can sit. It's quite different than CL (much
less of it, probably dynamically scoped). I suspect it is late 70s,
and somehow I thought it was done in Canada, but I'm really unsure
about that.

I think probably not really. The first serious lisp I used was
Cambridge Lisp, with a standard lisp on top of it, in order to run
SHEEP.

Yes, I used SHEEP a good deal about 14 years ago. It was (and I
suspect is still) very oriented towards calculations in General
Relativity, and specifically to the classification of exact solutions
to the field equations -- a non-trivial task and one well-suited to an
algebra system. I don't think it's *really* a general-purpose system,
although it's not hopeless by any means. When I used it there was
talk about gluing the REDUCE simplifier onto it which would have
resulted in a much more powerful system.
I wonder if anyone knows what SHEEP stands for?
