loading nulls into a varray with SQL Loader

Right I am trying to load some data using sqlldr into Oracle 9.

I have a table that contains a varray, which is declared thus: type CONS_PERIOD_VALUES as VARRAY (50) of NUMBER(13,5)

Now the thing is that I want the varray to be 'padded out' with nulls so that it always has 50 elements, i.e. if I put 40 values in, then there should be 10 nulls at the end.
but if I give it (where the first number is the number of elements to follow):

50,.0076,..........0076,.0074,.0075,.0075,.0073,.0078,.0074,.0072,"",""
it doesnt load it.  Same as:
50,.0076,..........0076,.0074,.0075,.0075,.0073,.0078,.0074,.0072,,

And if I give it this:
48,.0076,..........0076,.0074,.0075,.0075,.0073,.0078,.0074,.0072 I only get 48 values.

So how do I put nulls in the varray????
