Closely related to deleting a line is deleting a group of lines between two delimiters. Such cases are easily solved with perl's "flip flop" operator. The following code will not print out the lines between (and including) SKIP and CONTINUE: 
use strict;
use warnings;

while (<DATA>) {
   print unless /^SKIP\s$/ .. /^CONTINUE\s$/;
}

__DATA__
one
two
SKIP
THOUGH THEY DAYS ARE FEW, THEY'RE FILLED WITH TEARS,
AND SINCE I LOST YOU IT FEELS LIKE YEARS.
YES, IT SEEMS SO LONG
GIRL, SINCE YOU'VE BEEN GONE,
AND I JUST CAN'T GO ON
IF YOU WON'T SEE ME, (you won't see me)
YOU WON'T SEE ME. (you won't see me)
