76<p><em>Arguments</em> are symbols, numbers or subexpressions.  In other
77contexts arguments are sometimes called &ldquo;arithmetic operands&rdquo;.  In
78this manual, to avoid confusing them with the &ldquo;instruction operands&rdquo; of
79the machine language, we use the term &ldquo;argument&rdquo; to refer to parts of
80expressions only, reserving the word &ldquo;operand&rdquo; to refer only to machine
81instruction operands.
82</p>
83<p>Symbols are evaluated to yield {<var>section</var> <var>NNN</var>} where
84<var>section</var> is one of text, data, bss, absolute,
85or undefined.  <var>NNN</var> is a signed, 2&rsquo;s complement 32 bit
86integer.
87</p>
88<p>Numbers are usually integers.
89</p>
90<p>A number can be a flonum or bignum.  In this case, you are warned
91that only the low order 32 bits are used, and <code>as</code> pretends
92these 32 bits are an integer.  You may write integer-manipulating
93instructions that act on exotic constants, compatible with other
94assemblers.

96<a name="index-subexpressions"></a>
97<p>Subexpressions are a left parenthesis &lsquo;<samp>(</samp>&rsquo; followed by an integer
98expression, followed by a right parenthesis &lsquo;<samp>)</samp>&rsquo;; or a prefix
99operator followed by an argument.
