Range lists
Excel
allows all parameters to be range lists. Some examples are:
=SUM(A1,A3)
is the sum of two cells (function has 2 parameters).
=SUM((A1,A3))
is the same, but with one parameter being a range list.
=INDEX((A2:A3,C2:C3),1,1,2)
Calc
only allows range lists in the INDEX function. For example:
=INDEX((A2:A3;C2:C3);1;1;2)
returns the first cell of the second range in the range list.
