Mac – Progress for long scripts?

Now that I have the basic “Zip” process working, I want to be able to present the user with a progress bar. On windows I can do with this the “Test if Program Open” command and periodically look at the 7Zip log to find out where I am.

But in the Mac running the applescript seems hold Omnis Execution until it is done. Is this correct? Or am I just running so fast with the small sample files I am testing? In any case, the “Test if Program Open” command does not exist for the Mac. Is there something similar?

Thanks
