Nevermind, I got around it by 

DIM vArray as New Variant[]

	varray=["Cardinalities",.LocalCardinality,.TargetCardinality]
	csvRelData.Add(varray,"Cardinalities")
	varray=["Transpose",.LocalSliceMethod,.TargetSliceMethod]
	csvRelData.Add(varray,"Transpose"]
	etc

which only doubles the size of the code.  

But it would be nice if there was some way to cast an array as Variant[] :-)
