<P>This document describes both the <B>slsh</B> intrinsic functions and the
<B>slsh</B> library functions.  The latter functions are written in <B>S-Lang</B>
and make use of lower-level intrinsic functions that are described in
the 
<A HREF="http://www.jedsoft.org/slang/doc/html/slangfun.html">Intrinsic Function Reference Manual</A>.
As the <B>slsh</B> library functions make no use of <B>slsh</B> intrinsics, they
may be used by any conforming <B>S-Lang</B> application.  The <B>slsh</B> intrinsic
functions are specific to <B>slsh</B>.</P>
<P>Before a particular <B>slsh</B> library function may be used, the file that
defines the function must first be loaded.  The recommended mechanism
for loading a file is through the use of the
<CODE>require</CODE> function, e.g.,
<BLOCKQUOTE><CODE>
<PRE>
   require ("structfuns");
</PRE>
</CODE></BLOCKQUOTE>

will make the functions defined in the file <CODE>structfuns.sl</CODE>
available to the interpreter.  The <CODE>require</CODE> function itself is
defined in the file <CODE>require.sl</CODE>, which a conforming application
will automatically load.</P>
