OS/400 R440 has added support for stored procedures to use 
the SIGNAL function. This ODBC DLL contains new support 
to take advantage of this host feature. SQLSTATE and error 
message text defined in the stored procedures can now be 
accessed through the ODBC driver when calling SQLError.

In order to use this DLL you need to: 
 	
    1.- Stop any ODBC application that is using the Client 
        Access ODBC Driver. 

    2.- Rename the  previous CWBODBC.DLL file that is normally 
        located at:

        \Program Files\ibm\Client Aceess\Shared

        This path could  be different depending on where you
        specified to install Client Access Express.  

    3.- Download  this DLL  file and  copy it into the 
        directory where the original file was found. There is 
        no need to restart the computer. 

Notes: 

     Before  coping this DLL file,  it is highly recommended  
that the latest Client Access Service Pack be installed on 
your PC.
