_DIARYDATE System Variable
Contains the current date in the Calendar/Diary.
_DIARYDATE = dExpression
Parameters
- dExpression
Specifies the date for the Calendar/Diary.
Remarks
With _DIARYDATE, you can display the Calendar/Diary with a specific date selected, or you can return the selected Calendar/Diary date.
By default, the current date is stored in _DIARYDATE. When you open the Calendar/Diary, the current date is selected. You can store a different date to _DIARYDATE so that the Calendar/Diary opens with this new date selected.
Selecting a new date when the Calendar/Diary is open causes the new date to be stored to _DIARYDATE. When you close the Calendar/Diary, _DIARYDATE contains the last selected date.
Example
In the following program example, the Calendar/Diary opens with March 28, 2001, selected and the value of _DIARYDATE appears below. July 4, 1776, is then stored to _DIARYDATE and _DIARYDATE displays again. The program then uses the DATE( ) function to select the current date, and displays _DIARYDATE.
