: Hmm, will have to think about this alot.... Have been using the "worms"
: test program from ncurses to test things. That contains alot of "goto
: X,Y; Plot a Char; goto X,y; Plot a Char, etc" So that could be several
: tens, hundreds of K of data for a single screen, if the user was to let
: it run.... Because it doesn't technially scroll the screen....
:
: ideas, anyone?
You're confusing current screen refresh with scrollback. Anything
drawn on an 80x24 screen needs to be saved for refresh.
Scrollback addition is only required when the terminal emulator
scrolls it's screen by some number of lines. Those lines scrolled
off the top are added to the scrollback buffer.
