Safe Browsing in a Strongly Typed Persistent Environment

The need to examine data structures often occurs in programming language and database management systems. In this paper we describe how a browser for a strongly typed programming language ( PS-algol ) may be written in a type secure manner in a closed persistent environment. This is achieved without resorting to magic or having to break the type rules of the language by exploiting a compiler that is a object with full civil rights in the environment. The use of impact of such an object is discussed. Safe Browsing in a Strongly Typed Persistent Environment Page 3
