27* =============

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