System.ClosingDate(Date) Method

  • Article

Version: Available or changed with runtime version 1.0.

Gets the closing date for a Date Data Type.

Syntax

ClosingDate :=   System.ClosingDate(Date: Date)

Note

This method can be invoked without specifying the data type name.

Parameters

Date
 Type: Date
The input date.

Return Value

ClosingDate
 Type: Date

Remarks

All dates have a corresponding closing date. A closing date is a period in time following the given date but before the next regular date. Closing dates are sorted immediately after the corresponding regular date but before the next regular date.

xxxxxxD: Regular date

xxxxxxC: Closing date

The compiler cannot convert the expression xxxxxxC to a Date data type. Therefore, you must use the ClosingDate method to create a closing date.

Example 1

The first example shows how to use the ClosingDate method. A regular date is given as input.

var
    Date1: Date;
    CloDate: Date;
    Text000: Label 'The closing date for %1 is %2.';
begin
    Date1 := 20140404D;  
    CloDate := ClosingDate(Date1);  
    Message(Text000, Date1, CloDate);  
end;

The following message is displayed:

The closing date for 04/04/14 is C04/04/14.

Example 2

The second example shows some statements that do not work and explains why they do not work.

var
    Date1: Date;
    CloDate1: Date;
    CloDate2: Date;
    Text000: Label 'The closing date for %1 is %2.';
begin
    // Date1 := 20140404C;  
    // The previous statement does not compile because the compiler   
    // cannot convert '20140404C' to a Date data type.  
    Date1 := 20140404D;  
    // The previous statement compiles.   
    // The compiler converts '20140404D' to a Date data type.  
    // CloDate1 := ClosingDate(20140505C);  
    // The previous statement does not compile because the compiler   
    // cannot convert '20140505C' to a Date data type and the ClosingDate   
    // method requires a Date data type for its parameter.  
    CloDate1 := ClosingDate(Date1);  
    // The previous statement compiles.  
    // Date1 is a Date data type.   
    CloDate2 := ClosingDate(CloDate1);  
    // The previous statement compiles.  
    // CloDate1 is a Date data type.  
    Message(Text001, CloDate1, CloDate2);  
end;

The following message is displayed:

The closing date for C04/04/14 is C04/04/14.
