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

ed
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.
