NAME

uc - return upper-case version of a string


SYNOPSIS

uc EXPR

uc


DESCRIPTION

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 $_.
