I am writing a skill program that at one point uses a skill procedure defined by a different skill program. Because of this, I want a way to test to see if the procedure I want to use has been defined. If it hasn't been defined yet, then and only then do I want to load the other program. If the procedure is defined, I do not want to waste the time loading it again. Is there a way to test to see if a procedure is already defined?
