#print
So far you have always dealt with one file at a time.  Suppose you
wanted to combine two files - there is nothing we have covered so far
that will do that.  But the editor does have a command 'r' (read)

r file

which reads in the contents of "file" without throwing away what
you already have.  So that you can combine the files "cat" and "dog"
(and name the result "animal") by saying

ex
r cat
r dog
w animal
q

In this directory are four files named for continents.  Combine them into
one file named "world".  (Read the files in alphabetical order,
as they are listed).  You may want to list the input files and the combined
files with "cat" to see what they look like.
When done, type "ready" as usual.
