/*  Purpose */
/*  ======= */

/*  This subroutine translated from a character string specifying a */
/*  upper- or lower-triangular matrix to the relevant BLAST-specified */
/*  integer constant. */

/*  ILAUPLO returns an INTEGER.  If ILAUPLO < 0, then the input is not */
/*  a character indicating an upper- or lower-triangular matrix. */
/*  Otherwise ILAUPLO returns the constant value corresponding to UPLO. */

/*  Arguments */
/*  ========= */
/*  UPLO    (input) CHARACTER */
/*          = 'U':  A is upper triangular; */
/*          = 'L':  A is lower triangular. */
/*  ===================================================================== */
