27 Description
28  A keyword and a list of tokens is a 'dictionaryEntry'.
29 
30  An dictionaryEntry can be read, written and printed, and the types and
31  values of its tokens analysed. A dictionaryEntry is a high-level building
32  block for data description. It is a front-end for the token parser.
33  A list of entries can be used as a set of keyword syntax elements,
34  for example.
