| %U | 
This command causes Natural to translate lower-case characters to upper-case for alphanumeric input data.
Upper-case translation is in effect by default.
%U influences the interactive input, which
                          is entered, for example, with a Natural INPUT statement. It does not,
                          however, influence the input from the stack.
               
Upper-case translation is not performed if
                          AD=W has been specified for the input field (see the
                          section
                          Field
                             Upper/Lower Case Characteristics in the description of the
                          session parameter AD).
