Hi, I make AAT script in Japanese.
I want to divide experiment trials in 10 blocks.
And, I want to analyze for each blocks separately.
Please teach me How should I wright script.

You need to be more specific. How many trials per block? Should item selection be reset between blocks? etc.
In general, what you'll want to do is:
(1) If you haven't already done so, work through the tutorials in the Inquisit documentation to learn the basics of Inquisit syntax.
(2) Based on the knowledge acquired in (1), work through the original AAT script until you sufficiently understand what it does / how it works. The comments included in the script will help with that. If you have trouble understanding any specific portion of the code, don't hesitate to ask about it here.
(3) Once you're done with (2), you should be able to modify the script according to your needs.
Some further remarks: The <expt> elements in the AAT run three blocks:
<expt>
...
/ blocks = [1 = SequenceGenerator; 2 = practice_AAT; 3 = AAT]
...
</expt>
<block AAT> is the "test" block. It runs 80 AAT trials.
<block AAT>
/ onblockbegin = [values.index = 0]
/ trials = [1 = instructions; 2-81 = AAT_start]
</block>
You can either add additional <block> elements to the script and run them via the <expt>s or run <block AAT> several times. You ought pay attention to any variables used throughout the script (<values> entries; e.g. values.index in the above) and make sure you either appropriately reset them between blocks or keep them intact. To understand those, refer to (2) above.

Dear Dave
Thank you for A clear explanation.
Now, I'm learning Inquisit script.
I'll callenge "try and error"!
I think about AAT experiment following.
1. 200 exp trials
2. 10 or 8 blocks
3. 20 or 25 trials / block
4. Three stimulus categories (Nega * 8 or 10, Neutral * 8 or 10, Posi *8 or 10)
