Speaking of logo sources, I've tried to get to anarres.cs.berkeley.edu
and my machine can't seem to find it. Anyone (Brian, maybe?) have the
Internet address? Thanks a bunch.

> A new alpha test release (version 2.8) of Berkeley Logo is now
> available by anonymous FTP. This version fixes several important
> bugs (the one about spaces at the end of a line, for example).
> Its major new feature is an extended-memory capability for the PC.
>
> The PC distribution includes two executable programs. BL.EXE is
> similar to the earlier versions except for the bug fixes mentioned

> to take advantage of extended memory if you have it. This means that

> * It's free.

> * It comes with source files (in C).

> * Logo programs are completely compatible among Unix, PC, and Mac.

> Disadvantages of Berkeley Logo:

> * It's pretty slow.

> * It doesn't do anything fancy about graphics. (One turtle.)
