|
*>
|
|
*> \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.
