What do you mean by "recorded"?
If you want to add line numbers to your pages, go to Page Layout tab,
Page Setup group, Line Numbers.
If you want to see what line you're in as you type, right-click on the
Status Bar (bottom of the document window) and check it (and other
useful things) on the list that appears. (This appears to show only
the line on the present page, not a cumulative total.)
