APL2/X is an interface between APL2 and the X Window System®, built at the IBM Cambridge Scientific Center. This interface enables the full set of the X Window System Xlib calls and the related data structures to be used directly from programs written in APL2, thereby providing APL2 with a true, full-function windowing environment. The interface also deals with the broader and more general issue of how to call C programs from APL2. The interface and the experience of building it are described in some detail in this paper.
