|
||
twirling baton. If you output it with a single backspace between
|
||
characters, the baton spins in place. If you output the sequence BS SP
|
||
between characters, the baton spins from left to right. If you output BS
|
||
SP BS BS between characters, the baton spins from right to left. This is
|
||
also occasionally called a twiddle prompt.</p><p>The twirling baton was a popular component of animated signature
|
||
files on the pioneering PLATO educational timesharing system. The <b class="command">archie</b> Internet service is perhaps the best-known
|
||
baton program today; it uses the twirling baton as an idler indicating that
|
||
the program is working on a query. The twirling baton is also used as a
|
||
boot progress indicator on several BSD variants of Unix; if it stops,
|
||
you're probably going to have a long and trying day.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="twink.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../T.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="two-pi.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">twink </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> two pi</td></tr></table></div></body></html>
