Examples

The examples in this chapter are based on the following assumptions:

• The current month is January 2000.
• Working days are defined in calendar WORKDAYS which contains the following working days (indicated by Y) for January 2000:

      ---S-------------S-------------S-------------S-------------S---

       1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1

           Y Y Y Y Y     Y Y Y Y Y     Y Y Y Y Y     Y Y Y Y Y     Y

• Periodic calendar PERIDAYS contains the following periodic definition for January 2000. These examples assume that all other days of this calendar are blank.

      ---S-------------S-------------S-------------S-------------S---

       1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1 2 3 4 5 6 7 8 9 + 1

           B C A A B     B C A A B     B C A A B     B C A A B     B

• Start of the week is defined as Monday. Weeks start on the following dates in January 2000: 3rd, 10th, 17th, 24th, and 31st.
