Berkeley Logo (<A HREF="usermanual">download manual as text</A>)
(<A HREF="downloads/ucblogo.pdf">download manual as PDF</A>)
(<A HREF="announce">download readme</A>)
is a freeware interpreter that I wrote along with
several students. (Major contributors are Daniel van Blerkom, Khang Dao,
Michael Katz, Douglas Orleans, and Sanford Owings.)
<p>News! UCBLogo development has been taken over by wonderful chief volunteer
Josh Cogliati and bunches of other volunteers:
dmalec, Barak A. Pearlmutter, janekr, hosiet, reinerh, atehwa, kilobyte, pahihu
<p>The newest source tree is here:<br />

You can file bug reports in its issue tracker at Github.</p>
<TD valign="center"><IMG SRC="ucblogo3.gif"></TABLE>
<p>The current version is 6.2.2, posted 29 Dec 2021.</p>

<p>(If you think Logo is just a graphics
language for little kids, check out a
<A HREF="logo-sample.html">sample program</A>
that should impress you.)
<P>Also consider David Costanzo's
<A HREF="http://fmslogo.sourceforge.net/">FMSLogo</A>, an
updated version of George Mills' MSWLogo,
a multimedia-enhanced version for MS Windows based on Berkeley Logo.

design a logotype (an identifying symbol) for your organization, you're in the
wrong place. This is the Logo computer programming language for
learners!</SMALL>
