Even if you didn't know about ucfirst, it's easy enough to do with quoting: `"\u$_"` Or with a regex, if you didn't know about that either, but that's weird. `s/(.)/uc$1/e`	[reply] [d/l] [select]

or with substr `substr($s, 0, 1, uc(substr($s, 0, 1)));` [download] or `substr($s, 0, 1) = uc(substr($s, 0, 1));` [download]	[reply] [d/l] [select]

As long as we're getting silly ... `$s &= ~' ';` [download] (Warning: may not work for non-7-bit-ASCII letters such as accented characters, Cyrillic characters, or anything in EBCDIC. Or even any characters that aren't actually letters. But it is fun to do.)	[reply] [d/l]
