And, 0 is either '' -or- 0 ;)

Generally, people just use the not 0 = true, 0 or undef = false syntax.
So if you just change it to:
$seen = 1;
if($seen){
do something...
}else{
don't do it...
}
that would work. I think you can also declare constants for this if you
really want to, but it's not that big of a pain.

I can't say:
#!/yadayada/perl -w
use strict;
$seen = true;
if( $seen )
{
#whatever
}
else
{
#something different
}
I get a bareword error, I'm using perl 5.004_04. Does perl support booleans
like this, do I need to use a package?
Thanks in advance
-Ken
