Variant.IsCode() Method

Version: Available or changed with runtime version 1.0.

Indicates whether an AL variant contains a Code variable.

Syntax

Ok :=   Variant.IsCode()

Note

This method can be invoked using property access syntax.

Parameters

Variant
 Type: Variant
An instance of the Variant data type.

Return Value

Ok
 Type: Boolean
true if the AL variant contains a Code variable, otherwise false.

Example

The following example determines whether an AL variant contains a code variable. The code initializes the MyCode variable with a string value. The MyCode variable is assigned to the variant variable that is named MyVariant. The IsCode method determines whether the variant contains a code variable and stores the return value in the varResult variable. In this case, the variant contains a code variable so true is returned and displayed in a message box. The IsText Method (Variant) determines whether the variant contains a text variable. The return value is false because the variant does not contain a text.

var
    MyCode: Code[100];
    MyVariant: Variant;
    varResult: Boolean;
    Text000: Label 'Does the variant >%1< contain a code variable? %2.';
    Text001: Label 'Does the variant >%1< contain a text variable? %2.';
begin
    MyCode := 'A1297';  
    MyVariant :=  MyCode;  
    varResult := MyVariant.IsCode;  
    Message(Text000,MyVariant,varResult);  
    varResult := MyVariant.IsText;  
    Message(Text001,MyVariant,varResult);  
end;
