in thread returning data from a for() loop?

i'm trying to split them into individual characters with an arbitrary character inbetween each one (in this case, either "\n" or <br>
i did try to read up on map, but i need simpler explanations/examples than i found... so would it be split or map?

    I would use split... 
    my @chars = split(//, $string);

    When you call split with an empty pattern "//", it automatically splits into individual characters and returns that list of characters.

    To print the results out as you have, then do this... 

    print join("\n", split(//, $string)), "\n";

    The split() works as I stated above.
    The join takes each element of the list it is given in the second arguement and puts the first arguement after it, forming a string; Exception, then last item in the list does not get the first arguement appended to it -- that is why I added the last "\n".

      ah! thank you! i hadn't quite understood fully how those worked, just some simple ways to use them (which i didn't like); and yes that not only works, its way easier to read, too! (:
