Ü  DEFINE (Field Definition)

·         Factor-2 represents the name of referenced dataarea name referred by result field. It can be any external dataarea, *LDA, *PDA.

·         Result field represents any internal variable, a data structure, a data-area data structure, program status data structure, file information data structure or any program defined data area.

·         The result field is taken for operation IN and OUT in the program.
