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