Thanks for the tip.. I think something may not be installed properly as
when I basic length("cold") I get "4SCALAR(0x8167c28)" and not just the
number 4.

When I run your line of code I get the following:


Does this mean anythign to you?

	I'm guessing, and may be wide of the mark.

	Check your locale.  I don't know enough about locale to
	give any more detailed information.

	Check the length of your line, and whether there are any
	non-printing characters (eg NUL: 0x0) between '5' and '0',
	or any unexpected characters anywhere.

	Check whether the '0' is really a zero, or another character
	which somehow 'looks like' a zero.

	Inserting an additional line of code as follows may help with
	some of the above.

my $ReplayqueueFile = <$REPLAYQUEUEFILE>; warn join(':', map { ord $_ }
( split('', $ReplayqueueFile))), "\n"; if ($ReplayqueueFile =~ m/(\d+)/)
