<B><FONT SIZE="+2">U</FONT></B>.
<h3>(hexstr->bytes str)</h3>
Decodes the hex representation into a byte array.
<h3>(href table key)</h3>
The hash table is a one dimensional array of association lists.
<BLOCKQUOTE><PRE><TT>(define (href table key)
  (cdr (assoc key
	      (aref table (sxhash key (length table))))))</TT></PRE></BLOCKQUOTE>
<h3>(hset table key value)</h3>
Stores the value into the hash table slot indicated by key.
<h3>(html-encode str)</h3>
If str contains any special html characters (&lt;&gt;&amp;)
a new string is returned with these replaced by their cooresponding
representations &amp;lt; &amp;gt; &amp;amp;.
<h3>(if predicate-form true-form false-form)</h3>

depending on the result of evaluating the predicate form.
<h3>(intern str)</h3>

<h3>(lambda (arg1 arg2 ...) form1 form2 ...)</h3>

<h3>(larg-default list index default-value)</h3>
Reference the list according to index, but skipping over
strings that begin with a colon or a dash. If the list is not long enough
it returns the default-value instead. Most useful when used
with the *args* variable inside a main program.

<h3>(let (binding1 binding2 ...) form1 form2 ...)</h3>

<h3>(let* (binding1 binding2 ...) form1 form2 ...)</h3>

      (y (+ x 10)))
  (+ x y))</TT></PRE></BLOCKQUOTE>

of the first element of the list of the form <B>index=value</b>,
or the default-value if none are found. Useful when processing the
*args* value inside a main program.
<h3>(load fname noeval-flag search-flag)</h3>
If search-flag is true it looks for fname in the current directory
and then in the SIOD_LIB directory. The forms from the file are
parsed according to the "parser:xxx" directive at the begining of the file

otherwise the forms are evaluated.
