Hi,
Thanks for your comments..

I like to know what does the below represents..

$'

from `perldoc perlvar':

      $'      The string following whatever was matched by the last success-
              ful pattern match (not counting any matches hidden within a
              BLOCK or eval() enclosed by the current BLOCK).  (Mnemonic: "'"
              often follows a quoted string.)  Example:

                  local $_ = 'abcdefghi';
                  /def/;
                  print "$`:$&:$'\n";         # prints abc:def:ghi

              This variable is read-only and dynamically scoped to the cur-
              rent BLOCK.

              The use of this variable anywhere in a program imposes a con-
              siderable performance penalty on all regular expression
              matches.  See "BUGS".
