How to place characters in the ruby console at specific locations?

Is it possible to place characters on screen at specific locations?

If so, how is this done?

For example, placing a character at the top right of the screen might be done something like this: puts(40,0,"R") Assuming the screen is 40 characters wide, the origin of the coordinate system is at the top left, and the character 'R' is to be placed there.

I'm not sure if Workspaces even allows cursor positioning, but I found this:

It doesn't appear Workspaces has the 'curses' library, though.

string = "R" puts string.rjust(40)

Thanks for your reply. This is one way of getting characters positioned on screen, but it requires the entire screen be reprinted as well. I was looking for a way to position individual characters anywhere on the screen without refreshing/reprinting everything.
