print "Enter page Access";
chomp ($item = <STDIN>);
my @queue = split /\s+/, $item;
print "Enter a page frame";
$frame = <STDIN>;
if ( $frame >= 3 )
    $fifo = pop @queue;

    print "Remove FIFO item: $fifo\n";
    print "Final queue:\n  @queue \n\n";

Use "shift" to remove the first element.

$fifo = shift @queue;
