        !             2: Each 'w' command typed so far has written the edited material
        !             3: back on the same file that it came from originally.
        !             4: This can be changed by giving a filename on the 'w' command:
        !             5:   w camden
        !             6: will write the current editor buffer
        !             7: on file 'camden'.  What does the following
        !             8: sequence of commands do?

        !            20: the commands given above.  Check by printing
        !            21: both files with "cat" that they are the same.
        !            22: Type "ready" when done.
