Len is a commonly used ASP function that allows you to determine the number of characters in a string. In other languages, a similar function would be "length". Len takes in just one parameter:
* The string variable to operate on
The original string variable is not altered.
Let's say you have a string called UserName which is equal to "Lisa Shea". You want to know how long that string is, to help you cut it into two pieces. To do so, you would use:
NameLen = Len(UserName)
The result is that NameLen would be equal to 9.
