UCase is a commonly used ASP function that allows you to convert all characters in a string to their upper case versions. It only takes in one parameter:
* The string variable to operate on
The original string variable is not altered.
Let's say you have a form in which a user types in a model number. You then want to compare that model number against a database of models to get more information. You have millions of model numbers, so you don't want to do a drop down or something like that. But if the user starts typing in lowercase letters, say "xyg142" or "Xyg142", you will have trouble doing a search properly. So you use:
ModelNo = UCase(ModelNo)
That would turn both of the above examples into "XYG142" without the user having to think about which way they enter the information.
