To replace one or more lines with one or more new lines, use the c (change) subcommand. This actually deletes the lines you want to replace and inserts the new lines.

1. Enter:

   a1,a2c

   where:
   • a1 is the number of the first line to be deleted.
   • a2 is the number of the last line to be deleted.
2. Type the new lines, pressing <Enter> at the end of each line.
3. End the insert by typing a . (period) on a line by itself.
