- The <STRONG>setscrreg</STRONG> and <STRONG>wsetscrreg</STRONG> routines allow the applica-
- tion programmer to set a software scrolling region in a
- window. <EM>top</EM> and <EM>bot</EM> are the line numbers of the top and
- bottom margin of the scrolling region. (Line 0 is the top
- line of the window.) If this option and <STRONG>scrollok</STRONG> are
- enabled, an attempt to move off the bottom margin line
- causes all lines in the scrolling region to scroll one
- line in the direction of the first line. Only the text of
- the window is scrolled. (Note that this has nothing to do
- with the use of a physical scrolling region capability in

- and the terminal has either a scrolling region or
- insert/delete line capability, they will probably be used
- by the output routines.)
