Example

The following example determines whether an AL variant contains an Action variable. The MyAction variable is assigned to the variant variable that is named MyVariant. The IsAction method determines whether the variant contains an Action variable and stores the return value in the varResult variable. In this case, the variant contains an Action variable so Yes is returned and displayed in a message box. The IsCode Method (Variant) determines whether the variant contains a code variable. The return value is No because the variant does not contain a code.

var
    MyAction: Action;
    MyVariant: Variant;
    varResult: Boolean;
    Text000: Label 'Does the variant contain an Action variable? %1.';
    Text001: Label 'Does the variant- contain a code variable? %1.';
begin
    MyVariant := MyAction;  
    varResult := MyVariant.IsAction;  
    Message(Text000,varResult);  
    varResult := MyVariant.IsCode;  
    Message(Text001, varResult);  
end;
