Identifiers

An identifier is a sequence of characters of unlimited length that denotes either a function or a method name. An identifier always begins with one of the following characters:

• Any alphabetic character (based on the Unicode letter classifications)

• Underscore (_)

• Dollar sign ($)

• Exclamation mark (!)

FormCalc identifiers are case-sensitive. That is, identifiers whose characters only differ in case are considered distinct.

These are examples of valid identifiers:

    GetAddr 
    $primary 
    _item 
    !dbresult
