            [ADJUST\]ADJUST My_Data "My Command" /STEP S1 S2 .. Sn

        S1 S2 .. Sn are used to pass the unity vectors (steps) for the iteration
        on parameters P1 to. Pn. The default depends on the starting guesses Gi:
        Si  is  equal to abs(0.1 x Gi) or 0.1 if Gi is 0.0 . Poor choice of ini-
        tial steps may lead to non convergence. Too small steps  will  not  help
        converging  when  one starts too far from the solution.  Too large steps
        may lead to incorrect evaluation of the parameter  errors.  The  optimal
        step for the determination of the errors is about the error bar, so that
        all parameters become dimensionless.
