Data Descriptors: A Compile-Time Model of Data and Addressing
Data descriptors, which have evolved from Wilcox's value descriptors [Wilcox 71], are a notation for representing run-time data objects at compile time.
Data descriptors are convenient for representing addressing in Fortran (with static allocation and common blocks), in Pascal and Turing (with automatic allocation and stack frames), and in more general languages such as Euclid and PL/I.
Data descriptors are able to encode the addressing modes of typiccal computer architectures such as the IBM 360 and the PDP-11.
