  We describe the results of our recent work on the determination of the value
of the parameter $\Lambda_{\overline{MS}}^{(4)}$ and of the $Q^2$-dependence of
the Gross--Llewellyn Smith (GLS) sum rule from the experimental data of the
CCFR collaboration on neutrino--nucleon deep-inelastic scattering, using the
Jacobi polynomials QCD analysis. The obtained results are compared with the
information, available in the literature, information on the previous
experimental measurements of the GLS sum rule.
