[Edit: swap "proceeding" for "preceding." Engrish is hard.]
ビル: pronounced "biru" is a shortened word meaning building. ビール: pronounced "biiru" means beer.
"The nobasu character (ー) ordinarily lengthens the vowel sound directly proceeding it"
But did not know that it "had" to be directly followed by katakana. :)

The ー character is not used after kanji because their sound cannot be elongated.
