      <p>There are several commercial versions<a id="id2924356"
      class="indexterm" name="id2924356"></a> of TeX on the market.
      The advantage of commercial programs over free ones is that
      they provide an automated installation procedure and some
      level of technical support. There's no reason to believe that
      a commercial implementation of TeX is necessarily better than
      a free one (or vice versa, for that matter) because the
      source code for TeX is in the public domain.</p>

      <p>The following sections highlight several commercial
      implementations of TeX.</p>

      <div class="section">
        <div class="titlepage">

            ArborText</h2>
          </div>
        </div>

        <p>ArborText<a id="id2924394" class="indexterm"
        name="id2924394"></a> sells TeX<a id="id2924249"
        class="indexterm" name="id2924249"></a> for MS-DOS<a
        id="id2924260" class="indexterm" name="id2924260"></a>
        systems as well as an implementation of TeX for unix
        workstations. The ArborText previewer and DVI driver
        software are also available for both unix and MS-DOS
        systems. The following discussion is based on experiences
        with TeX version 3.14B, the MS-DOS implementation of
        ArborText's TeX package.</p>

        <p>The TeX package is a complete TeX implementation for
        MS-DOS. The additional utilities, <b>PLtoTF</b><a
        id="id2924296" class="indexterm" name="id2924296"></a>,
        <b>TFtoPL</b><a id="id2924310" class="indexterm"
        name="id2924310"></a>, and BibTeX<a id="id2924318"
        class="indexterm" name="id2924318"></a>, are also included.
        Neither MetaFont nor <b>MakeIndex</b> is provided.</p>

        <p>The default installation of TeX creates format files
        for Plain TeX and LaTeX. To be as fast as possible, TeX
        creates executable versions of TeX for each of these
        formats; these versions have the appropriate macro packages
        preloaded into the executable. You can use the standard
        notation to load alternate macro packages if you wish to
        save disk space.</p>

        <p>ArborText includes a lot of support for using TeX for
        non-English documents<a id="id2931362" class="indexterm"
        name="id2931362"></a>. Several files of international
        hyphenation patterns (English, French<a id="id2931375"
        class="indexterm" name="id2931375"></a>, German<a
        id="id2931383" class="indexterm" name="id2931383"></a>,
        Dutch<a id="id2931392" class="indexterm"
        name="id2931392"></a>, and Portuguese<a id="id2931400"
        class="indexterm" name="id2931400"></a>) are provided, as
        well as reprints of the TUGboat articles describing new
        features of TeX version 3.0 and virtual fonts.</p>

        <p>Designed for an MS-DOS environment having only limited
        memory, TeX uses a swap file (potentially located in EMS<a
        id="id2931415" class="indexterm" name="id2931415"></a> or
        XMS memory<a id="id2931426" class="indexterm"
        name="id2931426"></a>) to process large files. Several
        environment variables can be used to alter the size of
        internal TeX data structures when a new format is being
        produced. In terms of big and small versions, TeX can be
        configured either way. These choices are made when you
        create the format file however, so you will need to use
        iniTeX<a id="id2931434" class="indexterm"
        name="id2931434"></a> (included with TeX) to make a
        &#8220;bigger&#8221; TeX.</p>

        <p>One of the most interesting features of TeX is a
        quick-and-dirty preview mode provided by the TeX
        executable. After at least one page of your document has
        been processed, you can switch to a preview mode and see
        what the page looks like while TeX continues processing
        your document. This previewer is not particularly
        attractive, but it's quick and easy to use. No other
        previewer is provided. ArborText sells a fully functional
        previewer as a separate package.</p>

        <p>To print your documents, you must purchase or obtain a
        DVI driver separately. ArborText sells two drivers, one for
        HP LaserJet printers and another for PostScript printers.
        The TeX distribution includes a complete set of
        <tt>TFM</tt> files, but it does not include any <tt>PK</tt>
        files.</p>

        <p>The ArborText previewer is summarized in the section
        called &#8220;<a href="ch09.html#sec.arb.preview"

        TeX by Y&amp;Y Inc.<a id="id2931622" class="indexterm"
        name="id2931622"></a> (a 386 or higher processor is
        required). \yyTeX is sold as a bundled package with
        <b>DVIWindo</b><a id="id2931641" class="indexterm"
        name="id2931641"></a>, <b>dvipsone</b><a id="id2931655"
        class="indexterm" name="id2931655"></a>,<sup>[<a
        id="id2931663" name="id2931663"
        href="#ftn.id2931663">126</a>]</sup> and a set of
        PostScript fonts (either the Computer Modern fonts, the
        Lucida Bright and Lucida New Math fonts, or the MathTime
        fonts). The installation provides format files for Plain
        TeX and LaTeX.</p>

        <p>\yyTeX stands out among TeX systems because of its
        memory management. Unlike other TeX systems, which exist in
        big and small versions, all of \yyTeX's memory management
        is dynamic. All of the buffers that TeX uses (main memory,
        font memory, string memory, etc.) will expand to meet the
        needs of the most complex documents you create. The memory
        required for hyphenation patterns is dynamically allocated
        as well, which means that you can construct multilingual
        formats with as many sets of hyphenation patterns as you
        need (multilingual formats are discussed in more detail in
        Chapter&#160;<a href="ch07.html"
        title="Chapter&#160;7.&#160;International Considerations">Chapter&#160;7</a>,
        <span class="emphasis"><em><a href="ch07.html"
        title="Chapter&#160;7.&#160;International Considerations">Chapter&#160;7</a></em></span>).
        The advantage of dynamic memory management over a fast and
        big TeX is that \yyTeX starts out small (big TeXs reserve a
        large fixed amount of memory even when processing simple
        jobs that don't require very much). In a multitasking
        environment where several programs are competing for
        memory, one large program can slow the progress of the
        entire system. \yyTeX's memory manager supports XMS<a
        id="id2931742" class="indexterm" name="id2931742"></a>,
        VCPI<a id="id2931757" class="indexterm"
        name="id2931757"></a>, and DPMI<a id="id2931765"
        class="indexterm" name="id2931765"></a>. This means that it
        can run under MS-DOS with any of the common memory managers
        and under Windows, Windows NT, and DOS sessions in OS/2<a
        id="id2931776" class="indexterm" name="id2931776"></a><a
        id="id2931789" class="indexterm" name="id2931789"></a><a
        id="id2931802" class="indexterm" name="id2931802"></a>.</p>

        <p>\yyTeX has a couple of additional strengths for
        multilingual use: it supports customizable input character
        translation and more than 255 internal font numbers. Most
        versions of TeX only support a maximum of 255 fonts in any
        single document.</p>

        <p>At the time of this writing, a new version of TurboTeX
        is actively being developed. Unfortunately, it was not
        available for review in time for this edition of <span
        class="emphasis"><em>Making TeX Work</em></span>. The Kinch
        Computer Company claims that the next release will include
        a big TeX running under Windows 3.1/Win32s and Windows NT
        as a native, protected-mode 32-bit application. A new
        Windows previewer will also be available, and it takes
        advantage of Windows &#8220;multiple document
        interface&#8221; to preview multiple documents in the same
        session. Kinch will also provide a set of the standard
        Computer Modern Fonts in TrueType and Type 1 formats.</p>

        PCTeX/386<a id="id2932582" class="indexterm"

        and the sources for Plain TeX, LaTeX, and AMSTeX. The PCTeX
        Laser System includes Big PCTeX/386, LaserJet, LaserJet 4,
        PostScript and DeskJet printer drivers (along with a
        complete set of Computer Modern fonts in <tt>PK</tt> format
        at 300dpi and 600dpi), and the <span
        class="emphasis"><em>PC TeX Manual</em></span>, in addition
        to everything contained in the Starter System.</p>

        <p>The discussion that follows is based on experiences with
        the PCTeX Starter System with PCTeX version 3.14 and the
        <b>PTI Laser/HP</b> DVI driver.</p>

        <p>In addition to the TeX executables and macro packages
        mentioned above, PCTeX includes these standard TeX
        utilities: BibTeX<a id="id2932675" class="indexterm"

        include any of the other standard utilities or the
        <b>MakeIndex</b> processor. MetaFont is available as a
        separate package (although it is being discontinued, so it
        may not be available for long).</p>

        <p>Several additional features make PCTeX an attractive
        commercial alternative:</p>

<pre class="screen">
FIXME:
</pre>
        </div>

        <p><b>Scientific Word</b> is a powerful program that might
        prove to be invaluable in some circumstances. An ideal
        candidate for <b>Scientific Word</b> is someone with little
        or no desire to learn TeX, but who wants professional
        quality output for documents containing a lot of
        mathematics. <b>Scientific Word</b> is not simply a fast,
        interactive previewer; it really is a visual editor that
        produces TeX code behind the scenes. You enter document
        elements (even complex elements like mathematics) in an
        interactive push-button fashion, and <b>Scientific Word</b>
        translates it into the appropriate LaTeX input. This is
        very different from Blue Sky Research's <b>Textures</b>
        where the user types in TeX but has nearly instantaneous
        feedback.</p>

        <p>Unfortunately, the complexity of TeX vastly exceeds
        <b>Scientific Word's</b> ability to act as a visual editor,
        and this leads to a number of potentially confusing
        discrepancies. For example, in a TeX document, the
        \parindent and \parskip control sequences control the
        indentation of the first line of a paragraph and the
        distance between paragraphs. In <b>Scientific Word</b>, the
        on-screen appearance of the document is controlled
        separately. This difference is apparent in Figure&#160;<a
        href="ch14.html#fig.sciword"
        title="Figure&#160;14.4.&#160;Editing a document with Scientific Word ">
        Figure&#160;14.4</a>, where the paragraphs appear to be
        indented with no additional space between them, and
        Figure&#160;<a href="ch14.html#fig.commercial.swpreview"
        title="Figure&#160;14.5.&#160;Preview of the Scientific Word document shown in Figure ">
        Figure&#160;14.5</a> (the same document shown in the
        previewer) where the paragraphs are not indented but have
        additional space between them.</p>

        <p>These discrepancies arise because <b>Scientific Word</b>
        was designed with the same philosophy as LaTeX: separation
        of content and form. The purpose of the <b>Scientific
        Word</b> editor is to allow you to organize your thoughts
        and perfect the content of your document. It is the job of
        LaTeX, in conjunction with the document style options that
        you select, to perfect the appearance of your document. The
        display shown in Figure&#160;<a
        href="ch14.html#fig.sciword"
        title="Figure&#160;14.4.&#160;Editing a document with Scientific Word ">
        Figure&#160;14.4</a> is not incorrect in any way, it just
        isn't WYSIWYG. TCI Research claims that &#8220;by going
        beyond WYSIWYG, <b>Scientific Word</b> allows you to focus
        on the creative process&#160;$&#8230;$ and not the layout
        commands necessary to typeset [your document].&#8221;</p>

        <p>When <b>Scientific Word</b> encounters TeX code that it

        amounts of customization do not require abandoning the
