Compiling APL: The Yorktown APL Translator

The Yorktown APL Translator (YAT) permits functions written in APL to be compiled using an existing compiler for part of the process. It also creates tables that allow the APL2 Release 2 interpreter to call the compiled code. The code can also be called from a Fortran main routine. This paper outlines the history of APL compilation, the motivation for producing YAT, the design choices that were...

Electronics Technology at APL

PL programs have made signifi cant and continuous use of electronics technology from the very beginning. In fact, the VT fuze was a marvel of the Laboratory’s electronics technology and the ingenuity of its practitioners. Electronics technology at APL can be subdivided into fi ve broad areas: microelectronics and advanced packaging, RF and microwaves, embedded computers and programmable devices...

Vehicle Technology at APL

ehicle technology at APL encompasses the four disciplines of guidance and control, navigation, aerodynamics/hydrodynamics, and propulsion as applied to military platforms and spacecraft. These disciplines are addressed in terms of historical background at APL, the status of current work, and examples of important new initiatives. The information was compiled for the Senior Leadership Team’s “Ve...
