<h3 class="section">Labels</h3>



   <p>A <dfn>label</dfn> is written as a symbol immediately followed by a colon

<code>:</code>.  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 <code>as</code> also

provides a special directive <code>.label</code> for defining labels more flexibly.
