Thanks for the comments Smoot.
I thought "while (<>) {...}" was the same as "foreach (<>) {...}". Is this
because foreach provides a list context to the file being read and while
provides scalar context? I read this in the camel book but didn't understand
the significance. It makes a difference

I'd appreciate any comments on the code below. I run it like this:
./live new("icmp");
foreach (<>)
{
chomp;
if ($_ eq "") {
print STDERR "\nDone\n";
exit(0);
}
print "$_ is ";
print "NOT " unless $p->ping($_, 2);
