We can probably give you better help if you tell us why you want to do this. However the following may be of use:

use strict;
use warnings;

my $file = <<FILE;
firstchance: Is there a method that will allow me to easly split a fil
+e into multiple files by blank line as seperator. Perhaps a module th
+at will make it easy

firstchance: can perl create virtual files for this process with the h
+elp of CPAN

tye: $/, 'paragraph mode' ?

Any advances?

;>
FILE

open my $in, '<', \$file;

local $/ = "\n\n";
my @parts = <$in>;

chomp @parts;
print "----------\n$_\n" for @parts;

Prints:

Note the use of an "in memory" file using $file (as suggested by CountZero) and the use of the special variable $/ to read blank line separated blocks as records (as suggested by tye).
