Module 3: COBOL Program structure


COBOL FIGURATIVE CONSTANTS

  • Figurative constants have some fixed names and the compiler has the ability to recognize these names and sets the corresponding values in the object program.
  • Example:-
          MOVE ZERO TO EMP-COUNT.
  • In above example, value ‘0’ will be moved to variable EMP-COUNT as compiler will recognizes ZERO and sets EMP-COUNT to ‘0’.
  • Given below are list Figurative constants and their description:-
