A pseudoclassical model to describe Weyl particle in 10 dimensions is
proposed. In the course of quantization both the massless Dirac equati
on and the Weyl condition are reproduced automatically. The constructi
on can be relevant to Ramond-Neveu-Schwarz strings where the Weyl redu
ction in the Ramond sector has to be made by hand. (C) 1997 American I
