The JCM uses translation tables to convert workstation characters to mainframe characters.
When an Open ServerConnect program receives a client request in Japanese that contains character datatypes, it gives control to the JCM. The JCM looks up the client character set in the translate tables.
If the JCM finds a translate table for the client character set, the JCM converts the data and names into the equivalent mainframe characters. After processing is complete, the JCM converts results back to the workstation characters before returning the results to the client.
If the client does not specify a character set in the login packet, or if the JCM cannot find a translate table for the client character set, the program fails, and Open ServerConnect sends the client an error message.
