WSformat is a formatting and printing program for Wordstar (DOS) files. WSedit and WSformat together are a full-featured word processing suite, running under current operating systems, but based on the Wordstar DOS philosophy ('what you see is what you want' and not 'what you see is what you get'). Nevertheless, WSformat does have a provision for document preview.

Wordstar Compatiblity: WSformat accepts all Wordstar (DOS) files, but does not support all Wordstar DOS functions, i.e., those which were added after Wordstar Version 4. Instead, some extended functions (such as generating tables of contents or handling footnotes) are implemented in a WSformat-specific way. Basic Wordstar 5-7 'symmetrical sequences' are recognized (indentions, for example).

WSformat supports hyphenation, the creation of end notes and footnotes, generation of tables of contents and indexes, line drawing, embedding graphics in text and allows conditional statements. In contrast to the older versions of DOS Wordstar, document preview and printing use functions provided by the Windows (or OS/2) operating systems. This means you have access to the printers and type fonts which are installed on the operating system.

The WSformat command syntax is very similar to that of Hypermake. From a WS file, Hypermake will generate an equivalent file in RTF, Winhelp, HTML, IBM Help or Microsoft HTML-Help format.
