Notes


      Notes: Intended to make it easy to take a set of print
        statements in a program and change them to build up
        a text file. Uses the IDL string function in place
        of the print statement to handle the arguments. Can
        then return the text array built up from multiple
        fprint calls and use it elsewhere.
