30: *>
31: *> \verbatim
32: *>
33: *> This subroutine translated from a character string specifying a
34: *> upper- or lower-triangular matrix to the relevant BLAST-specified
35: *> integer constant.
36: *>
37: *> ILAUPLO returns an INTEGER. If ILAUPLO < 0, then the input is not
38: *> a character indicating an upper- or lower-triangular matrix.
39: *> Otherwise ILAUPLO returns the constant value corresponding to UPLO.
