Ok, I have been trying to understand this context stuff. I know have a
reason to. I created a function and have a "word" within a while function
embedded within. The problem is that the function does everything I want
the first time. However the "word" within the while function continues to
hold the last value. I can do a source on the function and see the last
value within. How can I have the function return the string value to
nothing at the end of exection.
