Overview to Transcoding
Transcoding is the process of converting a SAS file (its data) from one encoding to another encoding. Transcoding is necessary when the session encoding and the file encoding are different. Transcoding is often necessary when you move data between operating environments that use different locales.
For example, consider a file that was created under a UNIX operating environment that uses the Latin1 encoding, then moved to an IBM mainframe that uses the German EBCDIC encoding. When the file is processed on the IBM mainframe, the data is remapped from the Latin1 encoding to the German EBCDIC encoding. If the data contains an uppercase letter Ä, the hexadecimal number is converted from C4 to 4A.
Transcoding does not translate between languages; transcoding remaps characters.
In order to dynamically transcode data between operating environments that use different encodings, an explicit encoding value must be specified. For details, see Encoding Values in SAS Language Elements.
