perl splitting

Hi, I was wondering if this code is splitting what I think its splitting

#LINE: while (@bumps){
LINE:    while (<FIL>) { 
	my $line2 = $_;
	chomp $line2;        
	my @parts = split;
	my $rom_ref = $parts[0];
	my $signal = $parts[1];

I'm assuming the array parts is from FIL being split. Is this correct?
