@cisneros: I am looking for escape commands to use in bash/bourne shell scripting that allow for automatic scrolling of text within a defined scroll region.
My fall back method is without defining a region within which to display:
while read line
done < ThisOrOtherFile
@Tracy Tiger: not quite. It would be use of escape commands or tput commands (maybe) that limit text to within an area of the current screen. Kinda like a split-screen only split horizontally. It might take a terminal redef but if so I don't know which commands it might be. It could be a use of tput to extract a feature form the terminal definition.
