- to set a software scrolling region in a window. The <EM>top</EM> and <EM>bot</EM> param-
- eters 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 op-
- tion 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 the terminal, like that in the VT100. If <STRONG>idlok</STRONG> is
- enabled and the terminal has either a scrolling region or insert/delete
- line capability, they will probably be used by the output routines.)
