The lexical rules of the EPL grammar describe how sequences of characters are used to form the basic elements of the language, that is, identifiers, constants (string, numeric, and so on), operators, separators, white space, comments, and language keywords. These elements, after discarding any white space and comments, form the symbols used in the syntactical grammar of the language.
