+<h2>Environment Variables</h2>
+<p> The <b>Environment Variables </b> pane allows you to view the current User and System environment variables that will be used when any abld command is invoked. User variables are modified or added when a process is invoked. Read only system variables are listed. Variables and values in bold are items that have been modified from their default values.</p>
+<p>Some variables have special meaning, including:</p>
+<ul>
+ <li><span class="code">PATH</span> — will always place "<span class="code">${EPOCROOT}\epoc32\tools;${EPOCROOT}\epoc32\gcc\bin;</span>" at the front of the <span class="code">PATH</span> regardless of what it is changed to </li>
+ <li><span class="code">PATH</span>, <span class="code">EPOCROOT</span>, and <span class="code">*MW</span> variables — <span class="note">cannot be undefined as they are required for system builds</span></li>
+</ul>
