uc - Perldoc Browser
- #uc EXPR
- #uc
-
Returns an uppercased version of EXPR. If EXPR is omitted, uses
$_.my $str = uc("Perl is GREAT"); # "PERL IS GREAT"This function behaves the same way under various pragmas, such as in a locale, as
lcdoes.If you want titlecase mapping on initial letters see
ucfirstinstead.Note: This is the internal function implementing the
\Uescape in double-quoted strings.my $str = "Perl is \Ugreat\E"; # "Perl is GREAT"
