Identifiers
An identifier is a character sequence composed of a combination of the following characters:
*The 26 letters of the Roman alphabet in upper and lower case
*Digits 0 through 9
*Underscore character (_)
*Dollar sign ($)
The first character must not be a digit. Identifiers are case sensitive. An identifier must not have the same spelling as a keyword. For example, the word action is a keyword and cannot be used as an identifier. An identifier can also contain a hash symbol (#) as the first character. This is helpful if you want to use a keyword as an identifier. See also Keywords.
