Abstract

A method is described which provides the information developer a map of transfer controls in the flow of an information presentation. The Online Presentation Control Language (OPCL) is a programming language designed to create stand-alone online presentations. An information developer, typically a non-programmer, uses the OPCL's commands to specify document structure, displayable text, sounds, animation, and other parts of the presentation. The Online Presentation Development System (OPDS) is a group of programs designed to create stand-alone online presentations. Online presentations include such items as product demonstrations, tutorials, and other programs in which the computer is used to present information.

Mapping Transfer Controls in an Online Presentation Command Language Compiler Listing

A method is described which provides the information developer a map of transfer controls in the flow of an information presentation. The Online Presentation Control Language (OPCL) is a programming language designed to create stand-alone online presentations. An information developer, typically a non-programmer, uses the OPCL's commands to specify document structure, displayable text, sounds, animation, and other parts of the presentation. The Online Presentation Development System (OPDS) is a group of programs designed to create stand-alone online presentations. Online presentations include such items as product demonstrations, tutorials, and other programs in which the computer is used to present information. The OPDS consists of three tools: -the OP Compiler which converts the OPCL into object format, -the OP Compressor which formats and compresses displayable picture elements of text and graphic shapes, and -the OP Processor which loads and executes the object code with its corresponding picture elements. There are two ways for control to pass from one section to another in the OPDS. The first is via linked sections, where the information developer specifies, per section, which, if any, section precedes and/ or follows the section being defined. The second is via the GOTO SECTION (GS) command. This command may appear anywhere in the SELECT phase of the presentation. In programmer terms, the GS command has the same effect as a GOTO command in most programming languages. Because information developers are typically non-programmers, the OPDS compiler produces a list of which sections GOTO which other sections so that the information developer can check on the flow that has been coded. The OPDS compi...
