Borcherds first introduced the so-called generalized Kac-Moody (GKM) algebras. Most of the results about ordinary Kac-Moody algebras can be generalized to these new algebras (cf. ref. [1] and §11.13 in ref. [2]). In the present note we discuss some properties about weight strings and weight sets of the module L(Λ) over a generalized Kac-Moody algebra.
