Before calling DBCHCL for the Initiate Request function and if the request contains
a USING modifier, the Teradata Database application program must build a data string.
The data string must contain the data described by the USING
modifier.
The data string is placed in Using Data Length.
Because DBCHCL does not parse the request string, it is the application program’s responsibility to check whether the request string contains a USING clause and to set Using Data Length appropriately.
