APRIL incorporates most of the facilities common to earlier interpreters and also includes several additional features. One new feature allows \"high-level\" routines, such as those used by the interpreter itself in the matching and cycling phases, to be actions in production rules: hence it is possible for the user to \"create\" an interpreter which is suitable for his particular domain. However, the most important features of APRIL are that: 1) memory is handled uniformly (Production Rules and data both being stored as\n states<\/jats:italic>\n ) and 2) APRIL allows Production Rules to retrieve and modify\n any<\/jats:italic>\n state. Together these latter features allow\n adaptive<\/jats:italic>\n systems to be implemented.\n <\/jats:p>","DOI":"10.1145\/1045343.1045361","type":"journal-article","created":{"date-parts":[[2007,1,17]],"date-time":"2007-01-17T18:32:02Z","timestamp":1169058722000},"page":"28-33","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["APRIL"],"prefix":"10.1145","author":[{"given":"M.
