The GetObjectByTag() NWScript command finds an object with the the indicated tag (specified as a string). It returns OBJECT_INVALID if no object was found. A common use for this command is to find an object with a unique tag (i.e. the object with the indicated tag), but it also handles multiple objects with the same tag. This command cannot be use to find the module object; use GetModule() instead. (All other types of objects can be found.)
