Barry,
Use the 'ref' function for this:
perldoc -f ref
One caveat, though: most uses of 'ref' seem wrong. Generally speaking, whenever I am
tempted to
use ref on vanilla code, I discover that I could simplify what I meant to do. In your
case, have
you considered making every value an array reference? If you only have a scalar, you
have a
one-element array ref. Generally, when I rework the code to eliminate the need for
'ref', I
discover that my code is shorter and easier to maintain.
I'm not saying that you've done anything wrong, of course. I'm just suggesting that
you might
want to give the code a second look.
Cheers,
Curtis "Ovid" Poe

Someone asked me how to count to 10 in Perl:
push@A,$_ for reverse q.e...q.n.;for(@A){$_=unpack(q|c|,$_);@a=split//;
shift@a;shift@a if $a[$[]eq$[;$_=join q||,@a};print $_,$/for reverse @A
