I want to have a running total on the display screen. How do I update a number on the screen so the new value shows in the same position as the previously displayed value?
Example:
---------------------
Total: 10 | <-- Imagine this is the display
---------------------
becomes
---------------------
Total: 11 |
---------------------
as opposed to
---------------------
Total: 10 |
Total: 11 |
---------------------
Example:
---------------------
Total: 10 | <-- Imagine this is the display
---------------------
becomes
---------------------
Total: 11 |
---------------------
as opposed to
---------------------
Total: 10 |
Total: 11 |
