#print
You can give addresses involving simple arithmetic
to move around in the file. For example,
3+1p
is the same as
4p
in the editor. Now that's not interesting, but
if the current line (".") is line 3, then
.+1p
is also 4p; it prints the next line. For example,
you can print the 3rd and 4th lines of this file
using
3p
.+1p
w
q
where "3p" prints the third line, as usual,
and then ".+1p" prints the next or fourth line.
Try that. Type "ready" when done.
