uc EXPR
uc
Returns an uppercased version of
EXPR. This is the internal function
implementing the \U escape in double-quoted strings.
Respects current
LC_CTYPE locale if use locale in force. See the perllocale manpage.
Under Unicode (use utf8) it uses the standard Unicode uppercase mappings. (It
does not attempt to do titlecase mapping on initial letters. See ucfirst for that.)
If
EXPR is omitted, uses $_.
