Progress bars

[Lars Brehmer]

Hi listers!

I can't seem to find a tutorial or any layman's explanations on putting 
a simple progress bar into my stacks.  I have a stack that imports text 
data and creates the cards to store it on.  If the file is large, it 
takes a while, so I'd like to build in a progress bars (on a separate 
subStack?) to give an idea how long the task will take.  Where does it 
go and how do you set it up? A tutorial or a sample stack that has one 
would be terrific! Can anyone help me out here?

Cheers!

Lars
