Im not familier with AS400 but i hope below code might help U.
you can view the created DSNs in the same registry locations mentioned in below code.

C#

public void CreateDSN(string dsnName, string description, string server, string driverName, bool trustedConnection, string database, string username)
 {
     RegistryKey DSNKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\ODBC\\ODBC.INI\\", true);

     RegistryKey DSNSubKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\ODBC\\ODBC.INI\\ODBC Data Sources", true);

     DSNKey.CreateSubKey(dsnName);

     RegistryKey DSNValuesKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\ODBC\\ODBC.INI\\" + dsnName + "\\", true);
     DSNValuesKey.SetValue("Database", database);
     DSNValuesKey.SetValue("Description", description);
     DSNValuesKey.SetValue("Driver", driverName);
     DSNValuesKey.SetValue("LastUser", database);
     DSNValuesKey.SetValue("Server", server);

     RegistryKey DSNValuesKey2 = Registry.LocalMachine.OpenSubKey("SOFTWARE\\ODBC\\ODBC.INI\\ODBC Data Sources\\", true);
     DSNValuesKey2.SetValue(dsnName, "Sql server");


 }
