Hi Tarl,

Thanks for the clarification on this. This was the conclusion I reached 
but from a slightly different perspective: i.e. it is the CIF client 
that passes the parameter block into the CIF interface. Hence if the 
client specifies 1 return argument then it is likely that only enough 
memory has been allocated for 1 argument, and so anything else should 
just be ignored to prevent memory buffer overruns.

ATB,

Mark.
