You can do that indirectly without using pcount() or parameters() (I seldom use them). When you don't pass a parameter, by "default" it is boolean false or simply empty() - in VFP .F. is empty.
Thus you could do this:

parameters tuSomeParameter
*tuSomeParameter = evl(m.tuSomeParameter, < valueYouwantAsDeafult >)
tuSomeParameter = evl(m.tuSomeParameter, .null.)
