Because of their style dependencies, efforts to create the equivalent of Reveal Codes in other word processors produced dissimilar results. clicking on a style token brings up the style editor with the particular style type displayed. The scheme provides a more detailed view to troubleshoot problems than with styles-based word processors, and object tokens can be clicked with a pointing device to directly open the configuration editor for the particular object type, e.g. The codes for formatting and locating text are displayed, interspersed with tags and the occasional objects, with the tags and objects represented by named tokens. The feature is a second editing screen that can be toggled open and closed and sized as desired. It allows a user to avoid retyping text created in other applications with formatting much different than what they need, or easy changes in the format of documents. Display of the codes, coupled with the ease of searching and replacing codes, is very powerful. It displays the codes and allow editing of the codes. Present since the earliest versions of WordPerfect, the Reveal Codes feature distinguishes it from other word processors Microsoft Word's equivalent is less powerful. text, whereas WordPerfect formatting codes consist of hexadecimal values. A difference between HTML tags and WordPerfect codes is that HTML codes can all be expressed as a string of plain text characters delimited by greater-than and less-than characters, e.g. Some data structures are treated as objects within the stream as with HTML's treatment of graphic images, e.g., footnotes and styles, but the bulk of a WordPerfect document's data and formatting codes appear as a single continuous stream. Documents are created much the same way that raw HTML pages are written, with text interspersed by tags (called 'codes') that trigger treatment of data until a corresponding closing tag is encountered, at which point the settings active to the point of the opening tag resume control. A key to WordPerfect's design is its streaming code architecture that parallels the formatting features of HTML and Cascading Style Sheets.
