Abstract

Windows 3.1 represents the biggest revolution to APL technology since the advent of full screen techniques. This creates a new challenge to APLers migrating their applications from mainframe or PC DOS environments into Windows 3.1. This paper describes an ease means to adapt existing and new applications to exploit Windows Graphical User Interfaces (GUI). By using the techniques described below one can utilize most GUI features without needing to comprehend the massive amount of detail typical to Windows programming. Additionally, any application will also be backwards compatible to the DOS character based screen interface.
