PM29334: String comparison from a RUIhandler returns incorrect result

APAR status

• Closed as program error.

Error description

• = chooseDrink,
  options =['soda', 'tea'], selected = 'soda'};
  
      function chooseDrink(e Event in)
          syslib.writeStdout('chooseDrink selected-?' +
  RadioGroup.selected + '?-');
          case
              when(RadioGroup.selected == 'soda')
                  syslib.writeStdout('selected: soda');
              when(RadioGroup.selected == 'tea')
                  syslib.writeStdout('selected: tea');
              otherwise
                  syslib.writeStdout('selected something
  different-?' +
                                  RadioGroup.selected + '?-');
          end
      end
  end
  
  Either at runtime or in preview mode selecting 'tea' produces
  the following output:
  chooseDrink selected-?tea?-
  selected something different-?tea?-
  Even though the Strings are equal the result of the comparison
  operation is not equal.
  
  Running with the debugger the returned selected value shown in
  the variables view is preceded by a hex value 3F( a square
  symbol). This character does not show on screen at runtime or in
  preview mode but it is this symbol which causes any string
  comparison to fail.
