in reply to full screen UI in perl

If you're displaying on an ANSI terminal, you can also use Term::ANSIScreen to move the cursor around. Here's a sample that clears the screen, prints "Hello" at column 10, row 10, pauses, then prints "Bye" on the same line.
use strict; use Term::ANSIScreen qw(:cursor :screen); $| = 1; cls; locate(10, 10); print "Hello"; sleep(1); locate(10,10); clline(); print "Bye"; sleep(1);

Update: Turned off buffering (which was causing some problems) and added example for clline.

    Wouldn't you be better off setting $| = 1 then printing without the newlines?
