    Purpose   
    =======   

    Sort the numbers in D in increasing order (if ID = 'I') or   
    in decreasing order (if ID = 'D' ).   

    Use Quick Sort, reverting to Insertion sort on arrays of   
    size <= 20. Dimension of STACK limits N to about 2**32.   

    Arguments   
    =========   

    ID      (input) CHARACTER*1   
            = 'I': sort D in increasing order;   
            = 'D': sort D in decreasing order.   

    N       (input) INTEGER   
            The length of the array D.   

    D       (input/output) REAL array, dimension (N)   
            On entry, the array to be sorted.   
            On exit, D has been sorted into increasing order   
            (D(1) <= ... <= D(N) ) or into decreasing order   
            (D(1) >= ... >= D(N) ), depending on ID.   

    INFO    (output) INTEGER   
            = 0:  successful exit   
            < 0:  if INFO = -i, the i-th argument had an illegal value
