Here's the top of the help page:
DESCRIPTION:
Returns an array filled with integers, each of which
identifies where in the current slice it is. This is a
generalization of the row and col functions: row(x) can be
expressed as slice.index(x,1) and col(x) can be expressed
as slice.index(x,2).
Doesn't sound too hard to duplicate. Do you want to try? I think a
careful look at the sweep function might help....
