This paper describes a simple tool for diagnosing allocation errors in C-language [Kern 78] programs. Our tool consists of a traced replacement for the standard memory allocator, and a program to analyze traces. We have found this tool quite helpful in making long-running programs (e.g. text editors) more robust.

PEN, a new portable video editor, uses a number of simple but effective techniques. Most are not new, but are unavailable in the literature. We will describe our goals for PEN's display module, discuss implementation alternatives and describe in detail the techniques used in the editor.
