ISDATE Function (Variant)
Indicates whether a C/AL variant contains a Date variable.
Syntax
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. |
MyDate := TODAY;
MyVariant := MyDate;
varResult := MyVariant.ISDATE;
MESSAGE(Text000,MyVariant,varResult);
varResult := MyVariant.ISCODE;
MESSAGE(Text001,MyVariant,varResult);
