1.  It's an interpreted language.. so no, it can't be compiled.  
saying that, you cna make a .dll out of it and call that -- but i  
haven't seen it done on a mac.

2.  Is there a sleep() or wait() function?  GOogle also suggests  
using: SendKeys "+", True -- have a look at send keys

3. I think David Empson is a fan of Soduku..
:)


I'd love to have a look over your code.. while not a fan of VBA, it'd  
be interesting to see it.  A while back I too looked into Soduku, and  
decided it looked like a job for a computer.
I had a play with what turned into <http://langabi.name/soduku.php>  
when it was a bit more buggy. PHP is a better language for me :)
