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
and the perlunicode manpage for more details about locale and Unicode support.
It does not attempt to do titlecase mapping on initial letters. See
ucfirst
for that.
If EXPR is omitted, uses $_
.
