      SUBROUTINE MB01SS( JOBS, UPLO, N, A, LDA, D )
C     .. Scalar Arguments ..
      CHARACTER          JOBS, UPLO
      INTEGER            LDA, N
C     .. Array Arguments ..
      DOUBLE PRECISION   A(LDA,*), D(*)
Arguments
Mode Parameters
  JOBS    CHARACTER*1
          Specifies the scaling operation to be done, as follows:
          = 'D':  row and column scaling with D, i.e., A will be
                  transformed to diag(D)*A*diag(D);
          = 'I':  row and column scaling with inv(D), i.e., A will
                  be transformed to inv(diag(D))*A*inv(diag(D)).
  UPLO    CHARACTER*1
          Specifies which triangle of the matrix A is stored, as
          follows:
          = 'U':  Upper triangle is stored;
          = 'L':  Lower triangle is stored.
Input/Output Parameters
  N       (input) INTEGER
          The order of the matrix A.  N >= 0.
  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
          On entry, the leading N-by-N upper triangular part
          (if UPLO = 'U') or lower triangular part (if UPLO = 'L')
          of this array must contain the upper triangular part or
          lower triangular part, respectively, of the symmetric
          matrix A.
          On exit, the leading N-by-N upper triangular part
          (if UPLO = 'U') or lower triangular part (if UPLO = 'L')
          of this array contains the corresponding triangular part
          of the matrix diag(D)*A*diag(D), if JOBS = 'D', or of the
          matrix inv(diag(D))*A*inv(diag(D)), JOBS = 'I'.
          The stricly lower triangular part (if UPLO = 'U') or
          stricly upper triangular part (if UPLO = 'L') is not
          referenced.
  LDA     INTEGER
          The leading dimension of the array A.  LDA >= max(1,M).
  D       (input) DOUBLE PRECISION array, dimension (N)
          The diagonal elements of the diagonal matrix D.
