RPG interface with C-BUS

[Eduard Sluis <eduard@xxxxxxxxxxxxxxxxxxxxxxx>]

Dear all,
 
We have to create a Interface to an application on the AS/400 that is using 
C-BUS as an Interface. Both applications are on the same AS/400.
As I understood C-Bus in this case is used as a wrapper around MQ-Series to 
provide extra security measures, although most of them is not used in our case 
the use of C-Bus would be the prefered way to go.
I also understood that C-Bus comes with an set of standard functions that can 
be used.
Although the other application has some documentation on how to invoke C-Bus 
functions I was searching the web and within IBM to get addtional information 
specially on how to invoke this functions from RPGLE but found an remarkable 
low total of hits.
Are there people amongst us that know where to get additional information on 
C-Bus or have experience with C-Bus with an RPG interface that care to share it?
That would be much appreciated.
 
Kind regards,
Eduard Sluis.
