Subject: Display a string in a given X,Y position

Hi everybody!

Sorry if this question has already been treated, I didn't succeed in
finding anything suitable for my needs.

I was trying to display the process of filling a board with given
patterns on a console.


#######################
#                     #
#                  X  #
#    X        X       #
#             X       #
#  X          X     X #
#                     #
#             X       #
#             X       #
#######################
(Just a stupid example)


I could'nt find anything better than doing :

system("clear")
showBoard

each time I wanted to update the display, even though I only wanted to
change a single char on the board!
Is there a way to tell Ruby to display a given string on a given X,Y
position, without changing anything else?

That would be perfect.


Thanks a lot for your attention,
(and thanks too for that wonderful programming language),

Eric
