 * Ash:When you are smoking by the window,you will see the ash flying...
 * ash is a microbot with the Cigaret's move scheme ... and a similar to Spark's gun.
 * SonAsh: a sonnet version of Ash,14 lines.Squeezed from FemtoAsh,so it performace same to FemtoAsh.
 *--------------------version 0.7 2003.9.14--------------
 * 0.7:first released version.With a mine version symbol PM.
 * Thanks kawigi for his open source nanobots,i learned much more from his bot FunkyFemto and FunkyMusic.
 *--------------------version 0.7 2003.9.15--------------
 * 0.8:Thanx Kawigi that told me how to make this runnalbe in JVM 1.3.
 *+++++++++++++++++++++++++++++++++Open Source+++++++++++++++++++++++++++
 * This bot is open source.
 * - Don't just copy-paste the code .
 * - Don't just copy-paste and then improve.(I don't want to fight modified versions of my own bot)
 * - Maybe some useful skill in this codes,if you use,Make your bot open source
 * - And preferably give credit.:)
 * If you want to know more or suggest,
 * email me or post messages on www.robochina.org or www.robocoderepository's forums.
 * every messages will be pleasent.

I suggest you make this bot compatible with Java 1.3 by adding a .toString() before the .charAt part. You should have noticed that in FunkyMusic? (which was my 5-line version of FunkyChicken). -- Kawigi

OK~~Thanx.~;] -- iiley

This sonnet development doesn't exactly help making our bot code more readable. =) -- PEZ

changed. Yes,you are right PEZ,i do not like to make sonnet,i like femto and haiku.~;]sonnet is worse than mini,so you can see there are only 2 or 3 sonnet this time but many femto. -- iiley

Sonnets are much more complex to write than a femto or haiku, that's for sure. Of course, David and I were agreeing that while the state of the art in nanos always gets simplified and shrunk, the state of the art in line-based bots will continually get more complex. -- Kawigi

That's partly because we now count semicolons I think. In any case, it's even more silly than minibot coding. But fun for a change. I like the immediate trade-off situations when producing haikus. -- PEZ

...or especially when making femtos. But you're right. It's self-code-obfuscation as an art. I suspect it will be almost comical to look at a Sonnet sometimes. -- Kawigi
