NOTE: Data file MYLIB.STK000001.DATA is in a format that is native to another host, or the file
      encoding does not match the session encoding. Cross Environment Data Access will be used,
      which might require additional CPU resources and might reduce performance.
WARNING: Some character data was lost during transcoding in the dataset MYLIB.STK000001. Either
         the data contains characters that are not representable in the new encoding or
         truncation occurred during transcoding.
