APL Windowing Systems - Where Next? Richard Nabavi MicroAPL Ltd Introduction The past three or four years have seen a great change in the user interfaces offered on small computers. Initially popularized by the Apple Macintosh, the mouse-driven, multi-window point and click style of interaction between the user and the machine is now becoming widely accepted, on machines varying from the Commodore Amiga and Atari ST through to multi-user networks of Unix workstations. IBM s adoption of Presentation Manager as the preferred front-end on its PS/2 range, and the important role that this has in SAA (Strategic Applications Architecture) indicates that windowing systems must be central to our plans for APL applications in the 1990s. However, adapting APL software - both interpreters and the applications which run under them - to the new style of user interface presents design challenges which the APL community is only just beginning to appreciate. Major changes will be needed both in the way in which APL programmers interact with the APL systems, and in the programming tools and style required to write APL applications which take advantage of the new environments on offer. Considerable work has been done in the former
