#print
So far you only know how to copy and print existing files
in the editor, and not how to get started from scratch.
The 'a' (append) command lets you type in new text.
For example, the sequence
  ed file
  a
  this is a new line of text
  .
  w
  q
will append the line
  this is a new line of text
to the editor buffer, and then write it on "file".
(If "file" doesn't already exist, the editor will
warn you, but it's not an error.)
Note that the material being added ends with the
line that just contains a single '.' and that normal
editor commands then resume.  Following this pattern,
make a file named "pres" that contains the
line

franklin delano roosevelt

and, after you have written it with a 'w' command,
and done your 'q', try saying "cat pres" to check that
you did it right.
Then type "ready".
