Hello,

I want to be able to print out data structures, without having the
environment blow up if the data structure is circular. One way to do
this is to limit the amount of characters the printer prints. Is this
possible in Common Lisp ?

The implementation I'm using is CLISP, though I suspect there can be a
standard way, since I want it to work for all my printing functions
(print, format, etc.)


Ouch, sorry for bothering the newsgroup. Had I only tried one another
google search, I would quickly turn up with:

(setf *print-circle* t)

Or:

(let ((*print-circle* t))
... your code here ...
)

and the rest of your CL-environment will not be affected.
