To apply a procedyre seqyentiaiy to elements of a list:

1. Enter the list.

2. Enter the frame index. This is the number of elements affected by

each iteration of the function. For example, entering 3 would take 3

elements from the list and use them as arguments for the function.

3. Enter the function.

4. Execute DOSUE.

Example: Find the 2-element moving average of { 1 2 3 4 5 }.

Step 1: Enter the list, the frame index, and the function.

ENDSUB.

Applying a Function Recursively to a List

To execute a function on every element of a list:

1. Enter the list.

2. Enter a program or function. A program or function that takes two

arguments and returns one result is ideal.
