A new alpha test release (version 2.6) of Berkeley Logo is now
available by anonymous FTP.  "Alpha test" means that I know there are
bugs in it!  But you're welcome to try it if you understand that.
I'm happy to get bug reports but I don't promise anything.

The new version fixes bugs that were reported to me in version 2.5,
and also implements tail recursion elimination, which should allow
larger programs to fit in smaller machines.  A very likely side effect
is that you may get misleading error messages (attributing the error
to the wrong procedure, for example); I'd like to know about these.

Users of version 2.5 under Unix should note that the new version does
not create a graphics window until the first graphics instruction is
entered, so don't panic when you start it up.

FTP to anarres.cs.berkeley.edu and get any of the following files:

pub/logo.tar.Z		Unix sources and documentation
pub/ucblogo.zip		PC version, PKZIP form, including executable BL.EXE
pub/ucblogo.sit.hqx	Mac version, StuffIt/BinHex form, w/ executable Logo
pub/usermanual		Just the documentation file.
pub/csls.tar.Z		Logo programs from _Computer Science Logo Style_

You're on your own for the unpacking software.

Advantages of Berkeley Logo:

	* 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.)

	* It still has bugs.  In particular, it runs out of memory easily.

If you don't have FTP access, but can read a 3.5-inch disk, send me
$2.50 to cover costs and tell me whether you want the Mac or the PC
version (or send $5.00 for both) and I'll send you a disk.
