Identifiers

Identifiers are the names of functions or variables. They start with a letter or an underline (_). Other letters, underlines, or numbers can follow afterwards. The exception to this are all characters that do not belong to the English alphabet, e.g. 'ä' or 'é'. There is no restriction for the length of an identifier. Furthermore, there is a distinction between capitalized letters and the use of small letters. For example, Name and name are two different identifiers.

Examples for valid identifiers: textFunc, _testVar2, new, NEW, New_12340

Examples for invalid identifiers: 12help, 1234, grösser, straße
