Suitability of recycled concrete aggregate for use in BS 5328 designated mixes

In this paper we will argue that pages on the World Wide Web can be made directly as programs in a functional programming language instead of through HTML or an HTML-based authoring tool. We use the Scheme programming language from the Lisp family for WWW page production. It is concluded that a Lisp language is an attractive direct vehicle for authoring of Internet material in the sense that the source of a WWW document becomes a Lisp program. Abstraction from details in the underlying markup language constitutes the main advantage in our approach. This is consistent with the expected advantage of introducing XML as a successor of HTML. In addition we find it useful to have the power of a high quality programming language available for automation of routine tasks during the authoring process.
