External Scripts and Parameters

Hi,

i setup some external scripts/tests on our xymon-Server (radius an smb).
for the radius check i have to take different parameters for the check 
(radius-secret and portnumber).
Is ist possible to pass these paramaters from the bb-hosts file to the 
external script?
like this: <ip> <hostname> # radius secret=xyz port=123
and how can i access this parameters in my script?
