Just test the name of the lisp function.
If the name returns nil it is not loaded.
This example assumes a lisp file "MyLisp.lsp" and a defun c:MyLisp

Code:

(if (not c:MyLisp)
  (load "myLisp.lsp")
)

or use

Code:

(or c:Mylisp (load "myLisp.lsp"))

or use

Code:

(autoload "myLisp.lsp" '("MyLisp"))

That is simple and to the point, it sounds like exactly what I am looking for, I will try it out and make sure it works for what I need, thanks
