DEFGLOBAL
=========


syntax: (defglobal <name> <initial-value>)

This function defines a global variable and
initialises it with an initial-value. It returns
the initial-value.

This function only exists in Babylon Lisp, not in
Common Lisp. In Common Lisp, variables can be defined
with DEFVAR!

example:       >(defglobal global 123)
               123
