   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.
