*> \par Purpose:
*  =============
*>
*> \verbatim
*>
*> This subroutine translated from a character string specifying if a
*> matrix has unit diagonal or not to the relevant BLAST-specified
*> integer constant.
*>
*> ILADIAG returns an INTEGER.  If ILADIAG < 0, then the input is not a
*> character indicating a unit or non-unit diagonal.  Otherwise ILADIAG
*> returns the constant value corresponding to DIAG.
