*  =============
*>
*> \verbatim
*>
*> 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.
