An iconic description language: programming support for data structure visualization
Kudang Boro Seminar, Robert N. Robson · ACM SIGCHI Bulletin · 1990
An icon description language, named DSIL (Data Structure Iconic Language), is described which facilitates the design of icons depicting data structures and accelerates the development of iconic interfacing tools for program visualization and debugging. By using the DSIL, different users can define or redefine their own icons to satisfy their needs. The DSIL has features of modern programming languages. It is hierarchical, modular, and provides adoption (inheritance). The design of the DSIL is based on the features of data structures in MODULA-2. The implementation of the DSIL in a data structure editor is presented.
