Hi, Juban, Nix, 2002-11-27 16:26:29
I think you missed a character in your letter. The line you mentioned
should be as follows:
while(1) { print $e[($i %= @e) ++], "\b"; }
^^ the "%" can't be omitted.
the modulo's values should be 0 to 3 and loops back again.
I think as long as the number of elements of the array doesn't overflow,
you can use it safely.
what do you mean by "auto flush"?
