DEFCONSTANT
===========


syntax: (defconstant <name> <value>)

Warning: Constants, which are produced with
         DEFCONSTANT can be changed in EMA-XPS 
         and babylon v3 in contrast to common lisp!

This function defines a constant with a value. This
value can not be changed. Local variables may not
have the same name like this constant has. The
function returns the name of the constant.

example:       >(defconstant constant 123)
               CONSTANT
               >constant
               123
