      This block applies the given function to each item of the given list, like the primitive MAP block, but with two differences:

1.  The # variable provided will contain the item number of the item currently being used in the given function: 1 for item 1, and so on.  You read the variable in your function; don't set it.

2.  You can provide more than one input list.  If so, the lengths of all the lists should be the same, and the function you supply must expect as many inputs as you have lists (i.e., that many empty input slots in the function).

      This block makes a new list containing selected items from the given list, like the primitive KEEP block.

What's different is that it provides the # variable for use in your predicate function.  It will contain the item number (in the original list) of the item being examined by the predicate.

      This block carries out the given script for each item of the given list, like the primitive FOR EACH.

What's different is that it provides the # variable, which will contain the item number in the list of each item in turn, 1 while processing item 1, and so on.
