Indicates whether a C/AL variant contains a Date variable.

Ok := Variant.ISDATE

Parameters

Variant

Type: Variant

Property Value/Return Value

Type: Boolean

true if the C/AL variant contains a Date variable; otherwise, false.

Example

The following example determines whether a C/AL variant contains a Date variable. The code initializes the MyDate variable with a Date value. The MyDate variable is assigned to the variant variable that is named MyVariant. The ISDATE function determines whether the variant contains a Date variable and stores the return value in the varResult variable. In this case, the variant contains a Date variable so Yes is returned and displayed in a message box. The ISCODE Function (Variant) determines whether the variant contains a Code variable. The return value is No because the variant does not contain a code. This example requires that you create the following variables and text constants in the C/AL Globals window.

Variable name DataType

MyDate

Date

MyVariant

Variant

varResult

Boolean

Text constant name Enu value

Text000

Does the variant >%1< contain a date variable? %2.

Text001

Does the variant >%1< contain a code variable? %2.

Copy Code
MyDate := TODAY;
MyVariant :=  MyDate;
varResult := MyVariant.ISDATE;
MESSAGE(Text000,MyVariant,varResult);
varResult := MyVariant.ISCODE;
MESSAGE(Text001,MyVariant,varResult);
