The 
.PN wsetscrreg
routine sets the scrolling region
for the named window.
Use these routines to set a software scrolling region
in a window.

the line numbers of the 
top and bottom margins of the scrolling region are contained in
.PN top
and 
.PN bot .
Line 0 is the top line of the window.

.PN scrollok 
are enabled, an attempt to move off the bottom margin line will cause all
lines in the scrolling region to scroll up one line.
Only the text of the window is scrolled.
