Typically, the Status Line displays whichever are relevant of the player's score, state of health, ammunition, location, orientation and time remaining to complete the current task.
The display is almost always above (or at the top of) the main window (though early FPSes are an exception). Sometimes it appears at the bottom of the main window. Some games even have it to side.note . Many games even have two status lines, usually at the top and bottom, or at both sides. The status line(s) may even be part of the main window itself.
"The Status Line" was also the name of Infocom's newsletter, after a certain publication took issue with its original name, "The New Zork Times".
