+#print
+Just as you can print several lines at once by
+giving a range of addresses with the 'p' command,
+you can delete several lines at once by giving
+two addresses.  For example,
+   2,5d
+deletes lines 2, 3, 4 and 5 of the current file.  The
+command
+   1,.-1d
+deletes all lines up to but not including the current line.
+And
+   1,$d
+deletes EVERY line.  (Use with extreme caution, obviously.)
+There is a file named 'counties' in this directory.
+Throw away the first five lines of it and rewrite it.
+Then type 'ready' as usual.
