What is the meaning of a dollar symbol ($) in SciLab?
EDIT:
What I meant was dollar symbol used in indexing lists. I assumed that's the single use of it.
Or to display some statistics at least. I need some statistics like this:
* All documents have root node with two children and
* 50% of the documents have product/picture node
* Documents have between 1 and 10 product/a/comment nodes
