Example
The following example determines whether an AL variant contains an Automation variable. The MyAutomation variable is assigned to the variant variable that is named MyVariant. The IsAutomation method determines whether the variant contains an Automation variable and stores the return value in the varResult variable. In this case, the variant contains an Automation 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
MyAutomation: Automation "AFormAut 1.0 Type Library";
MyVariant: Variant;
varResult: Boolean;
Text000: Label 'Does the variant contain an Automation variable? %1.';
Text001: Label 'Does the variant- contain a code variable? %1.';
begin
MyVariant := MyAutomation;
varResult := MyVariant.IsAutomation;
Message(Text000,varResult);
varResult := MyVariant.IsCode;
Message(Text001, varResult);
end;
