 Example movements:
*--------------------------------------------------------*
Go forward 3 times (e.g., following a formula):
+------+
| DATA |
+------+
| DATA |
+------+
| DATA |
+------+ <- Index at 3

Go back:
+------+
| DATA |
+------+
| DATA |
+------+ <- Index at 2
| DATA |
+------+
To go forward again along the same path, need to move the
pointer forward one spot and then jump to that location.
