For any one interested without downloading.. its just,
I figured a number of people would jump on this as being too trivial so let me just say this. It was one of the most downloaded examples in the Resource Center which suggests it's not as straight forward for people new to BYOND and/or interfaces. Secondly, it's more than just one line of code. You have to modify the interface window to get true full screen vs maximized.
Sorry, third post. And I noticed this demo is C style. That's cool but that's not how the majority of people on Byond write, evident by the official guide not being written using braces.
C-based languages aren't the only language that uses curly brackets.
* Note: Need to uncheck the main windows titlebar, statusbar, and optionally, the resize option.
