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.
