Take the string "alphaBETA", and demonstrate how to convert it to UPPER-CASE and lower-case.

Ada

with Ada.Characters.Handling; use Ada.Characters.Handling;
with Ada.Text_Io; use Ada.Text_Io;

procedure Upper_Case_String is
   S : String := "alphaBETA";
begin
   Put_Line(To_Upper(S));
   Put_Line(To_Lower(S));
end Upper_Case_String;

Forth

create s ,"alphaBETA"
s count type            \ shows: alphaBETA
s count 2dup upper type \ shows: ALPHABETA
s count 2dup lower type \ shows: alphabeta

JavaScript

alert( "alphaBETA".toUpperCase() );
alert( "alphaBETA".toLowerCase() );

Output:

ALPHABETA
alphabeta

Perl

my $string = "alphaBETA";
my $uppercase = uc($string);
