<h3 class="section">5.3 Stack Frames</h3>
<p><a name="index-Stack-frames-65"></a>
A <dfn>stack frame</dfn> is the run-time representation of a call to a
function; the frame stores the state that a function needs to remember
what it is doing. Frames have:
<ul>
<li><dfn>variables</dfn> (see <a href="Variable-Access.html#Variable-Access">Variable Access</a>), which are the values being operated
on.
<li><dfn>arguments</dfn> to the call (which are really just particularly
interesting variables).
<li>a current source location (see <a href="Source-Location-Printing.html#Source-Location-Printing">Source Location Printing</a>), which is
the place in the program where the function was running when it
stopped to call another function, or because of an interrupt or error.
</ul>
