Hi! I tried your package in a unix xterm window and it worked fine.
But could you explain how this procedure work? I'm a novice.
------------------------------------------
PROCEDURE ClearScreen IS
BEGIN
Put( CSI & "2J" );
END ClearScreen;
------------------------------------------
I understand that your CSI is equal to ESC & "[" , but why does the
output of the string "ESC[2J" cause a screen clear? Does it have something
to do with ANSI?
