<p>The authors describe CODE (computation-oriented display environment), which can be used to develop modular parallel programs graphically in an environment built around fill-in templates. It also lets programs written in any sequential language be incorporated into parallel programs targeted for any parallel architecture. Broad expressive power was obtained in CODE by including abstractions of all the dependency types that occur in the widely used parallel-computation models and by keeping the form used to specify firing rules general. The CODE programming language is a version of generalized dependency graphs designed to encode the unified parallel-computation model. A simple example is used to illustrate the abstraction level in specifying dependencies and how they are separated from the computation-unit specification. The most important CODE concepts are described by developing a declarative, hierarchical program with complex firing rules and multiple dependency types.</p>
