*
*> \par Purpose:
*  =============
*>
*> \verbatim
*>
*> This subroutine translates from a character string specifying a
*> transposition operation to the relevant BLAST-specified integer
*> constant.
*>
*> ILATRANS returns an INTEGER.  If ILATRANS < 0, then the input is not
*> a character indicating a transposition operator.  Otherwise ILATRANS
*> returns the constant value corresponding to TRANS.
