ab: Summary: {\it C. Lemarechal} [RR-78-4. Luxemburg, Austria: International
    Institute for Applied Systems Analysis. VII, 25 p. (1978; Zbl
    0398.90090)] suggested a descent method which combines a quasi-Newton
    method using a quadratic model with a generalized cutting plane idea.
    For this method we put a version into practice, which is slightly
    different from the original algorithm. This version has been encoded as
    a FORTRAN 77 program and tested for some examples on an MC68000
    computer. The results show that the code is reliable. The aim of this
    paper is to describe briefly our version and to provide some results of
    testing.
