Use the CCXLATE statement to specify a data set containing translate tables to be used for the control connection.
FTP looks first for an environment variable called _FTPXLATE_name. If the environment variable exists, its value is used as the data set name
Restriction: The environment variable name must be all uppercase, although the CCXLATE parameter can be in mixed case.
If the environment variable does not exist, FTP looks for a data set called hlq.name.TCPXLBIN.
CCXLATE FRED
If environment variable _FTPXLATE_FRED=FREDDYS.TABLES is defined for the FTP server, this statement specifies that the translate tables in data set FREDDYS.TABLES should be used for the control connection.
If there is no such environment variable defined, this statement specifies that the translate tables data set hlq.FRED.TCPXLBIN should be used.
