Text string ABC
Text string ABC
In this example, three text strings are rearranged in alphabetical order. The
original order is as follows:
D00100: Milk
D00200: Juice
D00300: Beer
When rearranged alphabetically, the order changes as follows: beer, juice,
milk.
Two text strings beginning with D00100 and D00200 are compared
in ASCII order from lower to higher. If the text string beginning with
D00100 is higher in ASCII order than the one beginning with
D00200, then the position of the two text strings will be reversed.
Two text strings beginning with D00200 and D00300 are compared
in ASCII order from lower to higher. If the text string beginning with
D00200 is higher in ASCII order than the one beginning with
D00300, then the position of the two text strings will be reversed.
