When the encoding of the
SAS session is different from the encoding of the SAS file or from
the data that resides in the SAS file, transcoding must occur. Consider
a SAS file that was created in the Western Latin1 encoding, then moved
to an IBM mainframe that uses the German EBCDIC encoding. In order
for the IBM mainframe to successfully access the file, the SAS data
file must be transcoded from the Western Latin1 encoding to the German
EBCDIC encoding. For information about transcoding concepts, including
SAS language elements that contain options for transcoding, see
Transcoding for NLS.
