       SSYTRS_AA_2STAGE

       Purpose:


            SSYTRS_AA_2STAGE solves a system of linear equations A*X = B with a real
            symmetric matrix A using the factorization A = U**T*T*U or
            A = L*T*L**T computed by SSYTRF_AA_2STAGE.

       Parameters
           UPLO

                     UPLO is CHARACTER*1
                     Specifies whether the details of the factorization are stored
                     as an upper or lower triangular matrix.
                     = 'U':  Upper triangular, form is A = U**T*T*U;
                     = 'L':  Lower triangular, form is A = L*T*L**T.
