I see you define something called $RS without also saying "use English;".
You're reading in a Unix text file, perhaps?  If so, no wonder it reads the
entire file, since it never finds the default input record separator, \015,
that it needs to tell it a line has ended.

Set $/ = "\012" and see what happens.  Or put a "use English;" at the
beginning of the script.
