generateUuid(variant: Integer): Binary;
The generateUuid method of the Application class generates and returns a binary Universally Unique Identifier (UUID) value, which can be used as an attribute of an object so that it can be exposed to third-parties.

| VariantMicrosoft | 3 | Reserved for Microsoft backward compatibility (GUID) |
| VariantNcs | 1 | Reserved for NCS (Network Computing System) backward compatibility |
The following code example shows the use of the generateUuid method.
create() updating;

self.uuid := app.generateUuid(VariantDce);
end;
