in reply to searching backwards in a string

Being new to perl, please dont flame me.
But, why cant you store the string in reverse in another string, and then work forwards...
Eg. 
my($str) = "abcdefgh";
my($str_rev);

print "before $str\n";
$str_rev = reverse($str);
print "after $str_rev \n";

[download]
This sets str_rev to "hgfedcba".

    i was thinking about that, but that's just horrid when you think about what's going on underneath compared to what the ideal case would be...

      For a "new" user of perl (me), its an adequate way round the problem until a person gains more knowledge.
      You shouldn't dismiss this out of hand.
