Abstract
Bianchi type-I cosmological models are discussed in the Bergmann-Wagoner-Nordtvedt scalar-tensor theory where both the so-called cosmological constant \ensuremath{\Lambda} and the coupling parameter \ensuremath{\omega} are taken to be functions of the scalar field \ensuremath{\varphi}. Exact solutions are obtained in Dicke's revised units assuming a very simple relationship between \ensuremath{\Lambda} and \ensuremath{\varphi}. The properties of the models are discussed in special cases.
