Why the sleep after each print? Are you perhaps suffering from buffering?

If not, my initial thought when I think about printing a string letter by letter would be:

$| = 1;
print $_ foreach (split '', $string);

Edit: I took a second look at the code you provided. I'm really not sure I understand what you're trying to do now. The second bit of the for loop is supposed to be a test that tells the loop when to stop, but since you're just assigning to $i, I'm pretty sure that loop will run forever.

Hmm... it prints out the string directly. I want it to instead of print "string", to make it so it has 1 second intervals between each character it's printing... But im going to read the article you linked me.

Ah, in that case, I think you were mostly on the right track except with the buffering thing and the end case for the for loop.

$| = 1;
foreach my $letter (split '', $string) {
    print $letter;
    sleep 1;
}

Somewhat obscure, but I think the following is cute:

sleep($|=print) for split '', $string;

print returns 1 if it's successful.
