Modern windowing user interfaces offer both a challenge and an opportunity to the APL programmer. This paper discusses some of the factors that need to be taken into account when designing APL applications in a windowing environment. In such an environment the application programmer needs to design the application to react to events which occur in the environment rather than design the application to take over the environment, especially when a number of independent applications are being run simultaneously. Some of the typical techniques required to produce a windowing application are discussed and applications examples are quoted using APL.68000 on the Apple Mac.
