<h2 id="netrexxc">NetRexxC</h2>
<h3>Description</h3>
<p>Compiles a <a href="https://www.ibm.com/software/awdtools/netrexx/library.html"
target="_top">NetRexx</a> source tree within the running (Apache Ant) JVM.</p>
<p>The source and destination directory will be recursively scanned for NetRexx source files to
compile. Only NetRexx files that have no corresponding class file or where the class file is older
than the java file will be compiled.</p>
<p>Files in the source tree are copied to the destination directory, allowing support files to be
located properly in the classpath. The source files are copied because the NetRexx compiler cannot
produce class files in a specific directory via parameters</p>
<p>The directory structure of the source tree should follow the package hierarchy.</p>
<p>It is possible to refine the set of files that are being compiled/copied. This can be done with
the <var>includes</var>, <var>includesfile</var>, <var>excludes</var>, <var>excludesfile</var>
and <var>defaultexcludes</var> attributes. With the <var>includes</var> or <var>includesfile</var>
attribute you specify the files you want to have included by using patterns. The <var>exclude</var>
or <var>excludesfile</var> attribute is used to specify the files you want to have excluded. This
is also done with patterns. And finally with the <var>defaultexcludes</var> attribute, you can
specify whether you want to use default exclusions or not. See the section
on <a href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the
inclusion/exclusion of files works, and how to write patterns.</p>
<p>This task forms an implicit <a href="../Types/fileset.html">FileSet</a> and supports most
attributes of <code><fileset></code> (<var>dir</var> becomes <var>srcdir</var>) as well as the
nested <code><include></code>, <code><exclude></code>
and <code><patternset></code> elements.</p>
<p>All attributes except <var>classpath</var>, <var>srcdir</var> and <var>destDir</var> are also
available as properties in the form <code>ant.netrexxc.<i>attributename</i></code>,
eg.<br/><code class="code"><property name="ant.netrexxc.verbose"
value="noverbose"/></code><br/> or from the command line as<br/><kbd>ant
-Dant.netrexxc.verbose=noverbose ...</kbd></p>
<p><strong>Note</strong>: This task depends on external libraries not included in the Apache Ant
distribution. See <a href="../install.html#librarydependencies">Library Dependencies</a> for more
information.</p>

<tr>
<td>crossref</td>
<td>Whether variable cross references are generated</td>
<td>No</td>
</tr>

<td>decimal</td>
<td>Whether decimal arithmetic should be used for the NetRexx code. Setting this to <q>off</q>

compiled</td>
<td>Yes</td>
</tr>
<tr>
<td>diag</td>
<td>Whether diagnostic information about the compile is generated</td>
<td>No</td>
</tr>
<tr>
<td>excludes</td>
<td>Comma- or space-separated list of patterns of files that must be excluded.</td>
<td>No; defaults to default excludes or none if <var>defaultexcludes</var> is <q>no</q></td>

</tr>
<tr>

</tr>
<tr>
<td>java</td>
<td>Whether the generated Java code is produced</td>

</tr>
<tr>
<td>keep</td>
<td>Sets whether the generated java source file should be kept after compilation. The generated

to change that.</td>
<td>No</td>
</tr>
<tr>
<td>logo</td>
<td>Whether the compiler text logo is displayed when compiling</td>
<td>No</td>
</tr>
<tr>
<td>removeKeepExtension</td>
<td>Tells whether the trailing <samp>.keep</samp> in <var>compile</var>=<q>false</q> mode should
