    Purpose   
    =======   

    This function is used to determine what eigenvalues will be   
    selected.  If this is part of the test driver ZDRGSX, do not   
    change the code UNLESS you are testing input examples and not   
    using the built-in examples.   

    Arguments   
    =========   

    ALPHA   (input) COMPLEX*16   
    BETA    (input) COMPLEX*16   
            parameters to decide whether the pair (ALPHA, BETA) is   
            selected.   

    =====================================================================   

       DOUBLE PRECISION               ZERO   
       PARAMETER          ( ZERO = 0.0E+0 )   
       COMPLEX*16            CZERO   
       PARAMETER          ( CZERO = ( 0.0E+0, 0.0E+0 ) ) */
