Secure application environments in APL\3000
Alan M. Marcum · 1979
Various mechanisms have been proposed for implementing secure applications (that is, a function or package of functions over which the author can maintain total control during execution, and whose possibly sensitive information can be protected). This paper describes another set of tools, a “Spaghetti Stack” with “Exception Handling,” for implementing secure applications. (A Spaghetti Stack is a means for capturing a State Indicator execution point, retaining the state, and executing from it later.)
