FUNCTION INTEGER-OF-DATE

Learn FUNCTION INTEGER-OF-DATE in COBOL through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.

12 min read • Advanced

FUNCTION INTEGER-OF-DATE is a focused COBOL lesson inside Numeric and Dates. The example uses the construct named in the lesson directly rather than reusing a generic placeholder.

Trace the example from its inputs through FUNCTION INTEGER-OF-DATE and identify the behavior that would change if that construct were removed or replaced. Pay attention to the language-specific rules shown by the syntax, because neighboring lessons intentionally exercise different mechanisms.

Topic-specific example

cobol-0067-034e14b03a.cbl

cobol Try It Live

       *> FUNCTION INTEGER-OF-DATE
       MOVE 68 TO WS-COUNT
       ADD 1 TO WS-COUNT
       DISPLAY WS-COUNT.

Edge case / engineering note

For FUNCTION INTEGER-OF-DATE, test one realistic boundary: empty data, invalid input, unavailable resources, lifetime/cleanup, type constraints, or concurrency timing where applicable. A successful happy path is not enough to prove the construct is used correctly.
