#print
In this directory is a file "outline".  Find the line that
begins "B.3.i".  Note that this line, and the next few
lines, should begin "A"... for  consistency.
(Print the whole file to see what is going on.  It's fairly short.)
Change all lines from the line beginning "B.3.i" to the line
beginning "B.3.v" to begin "A.3".  Then rewrite the file
and type "ready".

You got it right: I hope you found that the easiest
way to change the file would be with the commands
 /B.3.i/p
 .,/B.3.v/s/B/A/
or some such series.
