The <STRONG>scroll</STRONG> routine scrolls the window up one line. This involves mov-
ing the lines in the window data structure. As an optimization, if the
- scrolling region of the window is the entire screen, the physical
- screen may be scrolled at the same time.
+ scrolling region of the window is the entire screen, the <EM>physical</EM>
+ <EM>screen</EM> may be scrolled at the same time.
For positive <EM>n</EM>, the <STRONG>scrl</STRONG> and <STRONG>wscrl</STRONG> routines scroll the window up <EM>n</EM>
lines (line <EM>i</EM>+<EM>n</EM> becomes <EM>i</EM>); otherwise scroll the window down <EM>n</EM> lines.
