at this point it seems clear to me that i have no idea what i am doing.... after messing with this for the last hour the best i have gotten is

#!/usr/bin/perl -w
use strict;
my $thingy = "No Change\n";
print $thingy;

&change($thingy);

print $thingy;

sub change
{
  my $in = shift;
  $$in = "Changed\n";
}

I get the following error
Can't use string ("No Change") as a SCALAR ref while "strict refs" in 
+use at asdf.pl line 12

It seems like it is doing some sort of weird passing by value thing to me... but then I have no idea what I am doing (haven't you noticed...sigh) I read through perlref and it mentioned this problem existed but I could discern no answer also the 2 perl books I have on hand made similar statments with no answer I could find.

and I forgot to login, blast I guess today is not my day.......
