The simulation and use of a TABLE data type in algol W

This paper reviews the role of RECORD and REFERENCE variables in Algol W, points out some restrictions in their use, and describes a method for simulating a new TABLE data type within the existing syntax. It is shown how the use of a few simple procedures generated in a preprocessor phase enable this new type to be used freely within dynamic structures of data. A comparison is made with some alternative methods of implementation in Algol W.
