Identifiers

The character set for IDL identifiers comprises the alphabetic characters A to Z and a to z, the digits 0 to 9, and the _ (underscore) character. An identifier must start with an alphabetic character.

No IDL identifier can exceed 31 characters. In some cases an identifier has a shorter maximum length because the IDL compiler uses the identifier as a base from which to construct other identifiers; we identify such cases as they occur.
