                    DISPLAY "Student Failed"
           END-EVALUATE.

           STOP RUN.

Output -

Student got SECOND CLASS

Explaining Example -

In the above example: it evaluates the value of the variable WS-STD-GRADE using an EVALUATE statement.

  • If WS-STD-GRADE is "A", "B", "C", or "D", it displays "Student got FIRST CLASS".
  • If WS-STD-GRADE is "E" or "G", it displays "Student got SECOND CLASS".
  • If WS-STD-GRADE is "F", it displays "Student got THIRD CLASS".
  • If WS-STD-GRADE does not match any of the specified values, it displays "Student Failed".

It displays "Student got SECOND CLASS" because the WHEN "E" clause is satisfied.
