You've somehow got tr/// and regexes confused, or perhaps tr/// and split,
or perhaps you're just making stuff up. ;)
Regardless, split(/a-zA-Z/, $stat) splits the string $stat on the string
"a-zA-Z". Say, for example, $stat = "foo bar a-zA-Z baz qux". Your split
would result in the list ("foo bar ", " baz qux"). You were probably aiming
for the regex /[a-zA-Z]/, or better yet, \w, as in, split(/\w/, $stat), or
perhaps split(/\w+/, $stat).
Please read perldoc perlre and the regex sections of your books.
