Wilkinson, E.2016-04-052016-04-051986http://hdl.handle.net/10092/11987This volume consists of three separate reports. Part One - Project Report: The project report is written as a chronological account of my work on porting APL to the Macintosh. It explains the main difficulties which I encountered during the work but does not specify how to use APL nor any details about how MacAPL works internally. Part Two - User Manual: The MacAPL user manual is basically a port of the APL\ 11 manual , adapted to the new Macintosh version. It gives an introduction to using MacAPL but does not attempt to explain the APL language. References to books about APL are given in the Project Report. Part Three - Technical Manual: This is a short introduction to the inner workings of MacAPL. It explains the basic operation and mentions some of the data structures used. Hopefully it will be of some use to those who wish to modify and enhance MacAPL.enAll Rights ReservedDiscussion / Working PapersFields of Research::46 - Information and computing sciences::4612 - Software engineering::461204 - Programming languagesFields of Research::46 - Information and computing sciences::4613 - Theory of computation::461301 - Coding, information theory and compression
