*> \par Purpose:
*  =============
*>
*> \verbatim
*>
*> This subroutine translates from a BLAST-specified integer constant to
*> the character string specifying a transposition operation.
*>
*> CHLA_TRANSTYPE returns an CHARACTER*1.  If CHLA_TRANSTYPE is 'X',
*> then input is not an integer indicating a transposition operator.
*> Otherwise CHLA_TRANSTYPE returns the constant value corresponding to
*> TRANS.
