Maximize a window

[Bill Vlahos]

What is the command to maximize a window? The maximize icon in Windows  
doesn't behave the same as the green button on the Mac.

In Windows, the maximize button makes the window take over the entire  
screen in a single application mode. The other button makes it a  
resizable window. My application remembers the size of the window and  
if the last monitor was larger than the current one the resizable  
window is too big and i can't resize it.

On a Mac the Green button either makes the window fit the screen or  
fit the content.

I think I want a "Zoom" button in Windows to make the resizable window  
fit the screen. What command would that be?
