This function is used to switch to fullscreen mode.

This function is used to switch to fullscreen mode. This function was made in DarkGDK
but I converted it to DarkBasic. It was made for users of DarkGDK so that you could make it fullscreen because there are no settings like in DB Pro that let you make it start fullscreen. Also, with this, you can change the screen mode at the user's request.
