In HyperCode, the source code composing a program is presented in HTML format suitable for viewing with standard HTML browsers such as Mosaic. A HyperCode presentation of a program includes a top-level display providing links to each source file, and to the main function. In addition, a variety of links are added to the HTML to enable non-linear browsing; specifically, links between definitions and uses of major C language constructs assist programmers in comprehending program control flow, data structures, and other aspects of code organization.
