Abstract

This article describes a method which provides a means of enabling and disabling paging keys in an online presentation control language. 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.

Command for Disabling and Enabling Paging Keys in an Online Presentation Control Language

This article describes a method which provides a means of enabling and disabling paging keys in an online presentation control language. 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. The OPCL provides a command, the Define Paging command (.DP) which allows the information developer to designate which keys are to be recognized as the paging keys during the online presentation. There are four paging keys: Forward - which causes advance to the next panel (screen) Reverse - which causes return to preceding panel Escape - which causes return to the previous section Terminate - which causes termination of the online presentation For example, the programmer may designate the space bar as the forward paging key. When the document is processed online, pressing the space bar causes the next panel of the presentation to be displayed -- analogous to turning of a page in a book. The information developer is allowed to selectively disable or enable any defined paging key without changing the paging key itself. For example, if the space bar is the forward paging key, a method for disabling or enabling the space bar as a forward paging key is provided. While the space bar is disabled as a paging key, it can be used for normal input, such as text entry, or to cause a skip forward to a panel beyond the...
