Applescript Help Needed

I am not really sure where to post this.

I have been trying to learn Applescript .

One of the things that i want to be able to do is tell Photoshop to open up a default document in CMYK at 600 dpi and at a certain size with a transparent background.
I have got the size right, but try as i may I cannot seem to get CMYK and transparency to work. The other annoying thing is everytime i run the script I get a log file on my desktop which I would like to remove.

This is the script as it is at the moment:

tell application "Adobe Photoshop CS"
activate
set newDocRef to make new document with properties {width:3.606 as inches, height:2.362 as inches, resolution:600}
end tell

Any Ideas ?

Have you got a book on applescript there's a new one out called the applescript missing manual

Yes I have just a book by Hanaan Rosenthal, so hopefully I will learn more about scripting.

Luckily the answer to my question was discovered by my friend who has a background in C++.
