<h3 class="section">5.1 Labels</h3>
<p><a name="index-labels-210"></a>A <dfn>label</dfn> is written as a symbol immediately followed by a colon
<span class="samp">:</span>. The symbol then represents the current value of the
active location counter, and is, for example, a suitable instruction
operand. You are warned if you use the same symbol to represent two
different locations: the first definition overrides any other
definitions.
<p>On the HPPA, the usual form for a label need not be immediately followed by a
colon, but instead must start in column zero. Only one label may be defined on
a single line. To work around this, the HPPA version of <span class="command">as</span> also
provides a special directive <code>.label</code> for defining labels more flexibly.
