To see a quick preview of what is to come,
you can step through a simple program illustrating
which reveal the numbering system
that is underneath the machinery of characters
and strings. When you click on Forward and
Backward, a box showing results will change.
|a = ord('T')|
|b = a + 1|
|c = chr(b)|
|d = ord('a')|
|e = d + 25|
|f = chr(e)|
By running this example, you observe that the number representing the letter "T" is just one less than the number for "U".
