Abstract: The direct methods procedure MAGEX80 has been incorporated in MULTAN87 and proved to be useful programme for solving crystal structures. Here will be described some improvement and a new version of the procedure. An algorithm is used to select starting set reflexions which differs from the convergence method. By comparision with MULTAN82, the MAGEX87 takes less computing time and seems more efficient than the random starting-phase method.
