   29: *  =============
   30: *>
   31: *> \verbatim
   32: *>
   33: *> This subroutine translates from a BLAST-specified integer constant to
   34: *> the character string specifying a transposition operation.
   35: *>
   36: *> CHLA_TRANSTYPE returns an CHARACTER*1.  If CHLA_TRANSTYPE is 'X',
   37: *> then input is not an integer indicating a transposition operator.
   38: *> Otherwise CHLA_TRANSTYPE returns the constant value corresponding to
   39: *> TRANS.
