<h3>Installing the Downloaded Version</h3>

Digital Mars has a different view of installation than most software products.
It doesn't need registry entries, environment variable settings, nor does it
need to install anything in the \windows\system directory.
<p>

Consequently, the compiler can be run without any need for an install.
Just run the programs in \dm\bin. This is most convenient
for cases where a particular version of the compiler is needed, or to just try
it out.
<p>

Installing is as simple as going to the root directory of the hard disk and
unzipping the downloaded dm???c.zip file:
<pre>
	unzip dm???c.zip
</pre>
The compiler is \dm\bin\dmc.exe. Too make it even more convenient, add

<pre>
	c:\dm\bin
</pre>

to the PATH environment variable setting (c: is the drive it is installed on).

To compile a simple hello.c program:

<pre>
	\dm\bin\dmc hello
</pre>

will compile and link to create hello.exe.
<p>

Notes:

<ul>
	<li> To use <tt>&lt;iostream&gt;</tt> and other STL code,
	download <a href="ftp://ftp.digitalmars.com/Digital_Mars_C++/STL/stlport.zip" title="download STLport 4.5.3">
	STLport 4.5.3</b></a> as well. Be sure and use the switch:
<pre>
<tt>-I\dm\stlport\stlport</tt>
</pre>
	so that the compiler can find <b>&lt;iostream&gt;</b>.
	</li>

	<li> Do not install into a subdirectory with spaces, tabs,
	+ signs, commas,
	or # characters in the subdirectory or path names.
	</li>
</ul>
