     C* %NULLIND is used to indicate to the file object whether null is required   
     C* Note the ILE tags used to tell the compiler to use RPGIV.                  
     C* Note the special treatment of the binary field - the compile listing       
     C* from a previous compile was used to determine the correct internal         
     C* field name. (@B0003)
