                      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:

                      6: will write the current editor buffer
                      7: on file 'camden'.  What does the following
                      8: sequence of commands do?

                     13: writes it on file 'new'.  It has the same effect

                     18: In this directory there is a file named "old".

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