</h2>

<div id=xax_ style=MARGIN-LEFT:40px;MARGIN-RIGHT:40px;TEXT-ALIGN:left>

Lua is a small, fast, interpreted scripting language. Lua is the result of a merger of a configuration language (SOL) and a data entry language (DEL) . Lua's original goal was to be an extensible embedded scripting language inside software applications. Lua has been highly successful as an embedded scripting language and is used in many games, firmware and software applications. With the recent addition of modules, Lua now has a standard method to load libraries. Lua together with Lua libraries enables a complete standalone scripting language.&nbsp;<br id=eov43>

<br id=eov44>

Lua’s unique focus on extensibility, simplicity, efficiency and portability make it a small yet powerful scripting language. Lua is often used as a Domain Specific Language due to its small size, embeddability and portability.&nbsp; Lua supports a small set of general features and provides meta-mechanisms to allow the programmer to support programming styles of their choice.&nbsp;<br id=eov45>

<br id=eov46>

Lua was developed by Roberto Ierusalimschy, Luiz Henrique de Figueiredo, and Waldemar Celes at the Pontifical University of Rio de Janeiro (PUC-Rio), in Brazil.<br id=eov47>

<br id=eov48>

Lua means Moon in Portuguese, so be ready for libraries with references to space or the moon, and enjoy.<br id=jtwm1>

Lua for Windows is a 'batteries included environment' for the Lua scripting language on Windows.

Lua for Windows combines Lua binaries, Lua libraries with a Lua-capable editor in a single install package for the Microsoft Windows operating system. Lua for Windows contains everything you need to write, run and debug Lua scripts on Windows. A wide variety of libraries and examples are included that are ready to use with Microsoft Windows. Lua for Windows runs on Windows 2000 and newer versions of Windows. Lua and its associated libraries are also available for other operating systems, so most scripts will be automatically cross-platform. <a href=http://docs.google.com/RawDocContents?docID=dfxf6f4d_19gbt5shdb&amp;justBody=false&amp;revision=_latest&amp;timestamp=1213702923806&amp;editMode=true&amp;strip=true#top id=n_fq3 title="Back to top of document."></a>

<div id=q.bg0 style=MARGIN-LEFT:40px;MARGIN-RIGHT:40px;TEXT-ALIGN:left>

Lua is a simple yet powerful dynamically typed programming language. Lua is one of the fastest, if not fastest, interpreted scripting languages available, see <a href=http://dada.perl.it/shootout/craps.html id=cxsx136>http://dada.perl.it/shootout/craps.html</a>.<br id=eov447>

<br id=cxsx137>

<div id=gv-b0 style=MARGIN-LEFT:40px;MARGIN-RIGHT:40px;TEXT-ALIGN:left>

Lua has 8 basic types: nil, boolean, number, string, table, function, thread<span class=GramE id=cxsx139>,</span> userdata.<br id=t6:i>

<br id=gc7z>

Numbers are floating point values. Strings are non-mutable. Table is the basic data structure used to represent complex data.&nbsp;

</p>

<div id=q.bg1 style=MARGIN-LEFT:40px;MARGIN-RIGHT:40px;TEXT-ALIGN:left>

Lua has 21 reserved keywords: and, break, do, else, <span class=SpellE id=cxsx143>elseif</span>, end, false, for<span class=GramE id=cxsx144>,</span> function, if, in, local, nil, not, or, repeat, return, then, true, until, while.<br id=eov448>

<br id=cxsx147>

</div>

<div id=q.bg2 style=MARGIN-LEFT:40px;MARGIN-RIGHT:40px;TEXT-ALIGN:left>

Lua has 6 control structures: do end block statement, if statement<span class=GramE id=cxsx149>, </span>while statement, repeat until statement, for statement and break statement.<br id=t6:i0>

<br id=eov449>

</div>

<div id=fbdo1 style=MARGIN-LEFT:40px;MARGIN-RIGHT:40px;TEXT-ALIGN:left>

Lua has multiple assignments and&nbsp; return multiple values from functions.<br id=etui>

<br id=ky_50>

Lua has garbage collection, closures, tail calls, coercion, <span class=SpellE id=cxsx153>co-routines</span>, first order functions, meta-mechanisms and loadable libraries.<br id=t6:i1>

<br id=eov450>

Lua is a multi-paradigm language and uses meta-mechanisms to extend Lua to support different styles of programming including object-oriented and functional styles.<br id=c8c8>

<br id=n_fq69>

Lua is a very powerful; condensed scripting language.<br id=jtwm21>
