<tt>SMLofNJ</tt> implements a subset of the structure of the same name provided in Standard ML of New Jersey. It is included to make it easier to port programs between the two systems. The semantics of these functions may be different than in SML/NJ.
</p>
<ul>
<li>
<p>
<tt>structure Cont</tt> <br>
implements continuations.

</li>
<li class="gap">
<p>
<tt>SysInfo.getHostArch ()</tt> <br>
returns the string for the architecture.
</p>
</li>
<li class="gap">

<tt>SysInfo.getOSKind</tt> <br>
returns the OS kind.
</p>
</li>
<li class="gap">

<tt>SysInfo.getOSName ()</tt> <br>
returns the string for the host.
