uc - return upper-case version of a string

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. 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 $_.
