The most commonly used attributes of a calendar identifier are discussed below.

  • BEGIN DATE: The BEGIN DATE attribute should be used to specify the start moment of the time range that is considered in the calendar. The img_def_Wizard_button_bmp wizard will a display dialog box allowing you to specify a moment in time.

  • END DATE: The END DATE attribute should be used to specify the end moment of the time range that is considered in the calendar. The img_def_Wizard_button_bmp wizard will display a dialog box allowing you to specify a moment in time.

  • UNIT: The UNIT attribute is mandatory and is used to define the length of a single time slot in the calendar. The img_def_Wizard_button_bmp wizard will display a dialog box allowing you to select from one of the available time units.

  • TIMESLOT FORMAT: The TIMESLOT FORMAT attribute is used to specify the format of the elements in the calendar. The img_def_Wizard_button_bmp wizard will allow you to select from various predefined timeslot formats.

  • INDEX: The INDEX attribute is the place to declare indices in the current calendar. The img_def_Wizard_button_bmp wizard allows you to declare new index, delete or rename an existing index or move an index to another set.

  • PARAMETER: The PARAMETER attribute is like the INDEX attribute except that it allows you to declare scalar element parameters (instead of indices) in the current calendar.
