There are two predefined switches and one predefined counter which can be accessed from within a repeat over loop. These are useful in determining the following information about the loop:
In a repeat over, it is often useful to know whether the loop is at the first or last iteration. The predefined switches #first and #last can be accessed to determine this information. Each nested repeat over loop has its own #first and #last switches.
A program can also ask for the index of the current iteration by accessing the predefined counter #item. When repeat over loops nest, each instance has its own indices.
