%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).
