LTC1298 and Bascom 8051

[bufere]

Hi all,
Can anyone help me sort out the use of channel 0 and 1 thanks.
In the example of LTC1298 AD Convert by MCS does any one know how to switch channels from 0 to 1. 
The example works fine but uses only channel 1 & not being very good with ass & code etc atm I do not know how to control the channels independently yet.
If any one could show some code or shed some light on this subject it would be great.
The LTC1298 example by MCS can be found in the MCS example folder.
I need info for bascom 8051 NOT for AVR!.
Tankyou
