For reasons of clarity and accuracy, we like full English words and correct use of terminology.
This is a site for Beginners and Students. It can easily be a classwork/training exercise.
However, consider the person who arranged for the printing of 3m forms with a three-character box for noting some sequence number. By the time there were 1/4m of the forms left, the "we'll never exceed that" sequence number needed to be "increased". You can't make the box bigger, and there is a cost in trashing 1/4m forms. Plus analysis of system indicates no changes required to hold an alphanumeric field. So, you extend your sequence number by using the letters of the alphabet. You keep the 0-9 because humans are using the forms, and it is much easier to know that a number is in sequence than a letter.
