Re: Using variables in [data ...] statement

Ahhh.... I understand now.  
However:  I think this is a related question.

Trying to determine whether or not [data...] returns a value.  Snippet:

my $sname;
$sname="[data songs name $upc]";

if(length($sname)>0) {
	blah;
}

But upon inspection, length($data) ALWAYS returns 33.  Doesn't matter
what's in there.  $data always contains the correct stuff (i.e. song
name or nothing if not found), but length() never returns the length!  

On the other hand:

my $hi;
$hi="1234567";
length($hi);

returns 7.

Argh!  Please help.  I don't have to use length() to determine results;
if anyone has better ideas I'm quite open.  Thanks...
