<a name="index-operands-in-expressions"></a>
<a name="index-arithmetic-operands"></a>
<p><em>Arguments</em> are symbols, numbers or subexpressions.  In other
contexts arguments are sometimes called &ldquo;arithmetic operands&rdquo;.  In
this manual, to avoid confusing them with the &ldquo;instruction operands&rdquo; of
the machine language, we use the term &ldquo;argument&rdquo; to refer to parts of
expressions only, reserving the word &ldquo;operand&rdquo; to refer only to machine
instruction operands.
</p>
<p>Symbols are evaluated to yield {<var>section</var> <var>NNN</var>} where
<var>section</var> is one of text, data, bss, absolute,
or undefined.  <var>NNN</var> is a signed, 2&rsquo;s complement 32 bit
integer.
</p>
<p>Numbers are usually integers.
</p>
<p>A number can be a flonum or bignum.  In this case, you are warned
that only the low order 32 bits are used, and <code>as</code> pretends
these 32 bits are an integer.  You may write integer-manipulating
instructions that act on exotic constants, compatible with other
assemblers.
</p>
<a name="index-subexpressions"></a>
<p>Subexpressions are a left parenthesis &lsquo;<samp>(</samp>&rsquo; followed by an integer
expression, followed by a right parenthesis &lsquo;<samp>)</samp>&rsquo;; or a prefix
operator followed by an argument.
