Exception Handling in the Visual Programming Language Forms/3
Zee Pieter J. van, M Burnett Margaret · 1995
Exception handling is a general purpose tool found in many modern programming languages, but most work to date is based on textual languages. We present an approach to exception handling in a new context, the visual programming language forms/3. The visual nature of forms/3 supports an effective approach to exception handling without the use of new language constructs. We show that a visual programming language not only can support a robust style of exception handling with good software engineering characteristics, but also that it can do so without compromising the characteristics of simplicity, concreteness, and immediate feedback.
