   29: *  =============
   30: *>
   31: *> \verbatim
   32: *>
   33: *> This subroutine translates from a character string specifying a
   34: *> transposition operation to the relevant BLAST-specified integer
   35: *> constant.
   36: *>
   37: *> ILATRANS returns an INTEGER.  If ILATRANS < 0, then the input is not
   38: *> a character indicating a transposition operator.  Otherwise ILATRANS
   39: *> returns the constant value corresponding to TRANS.
