        !             4: is possible to arrange for a program to take its input not
        !             5: from the terminal but from a file.
        !             6: Most UNIX programs are written so that they will read either
        !             7: the terminal or from a list of filenames.

        !            15: Answer yes or no.
        !            16: #create junk
