Question: "progress bar" when typing "return"?

I'm working with lengthy computations in Maple right now and I was just wondering whether it it possible to display some kind of "progress bar" after you hit the return button to start the computation.

At least in the form that text is displayed (e.g. "now is a good time to drink your coffee, computation may take a while") BUT that vanishes after the computation is complete.

Please Wait...
