Subject: Re: Overwriting one Ruby array or arrays with another

Thanks for the reply

I gave a fairly basic example so that I could explain my needs. Perhaps
a little too basic. I'm also very new to Ruby.

Going forward the array of arrays may hold information such as ...

[1, 1, "X", "20120502"]

... so that I have a grid that will display an "X" at x,y coordinates
1,1 and also hold some metadata such as "20120502" which in this case
would be a date.

Ultimately I will be creating an HTML grid of variable size that will
house an "X" or "O". The date would be metadata that I'm hoping to
display when you hover over a box when viewing the grid/graph in a
browser.

If I can produce a hash of {[x, y] => xxxxx } which holds the values "X"
and "20120501" that would be OK with me.

Would the code for such a hash be something like this ...

{[1, 1] => ["X", "20120501"]}
{[1, 2] => ["O", "20120502"]}

... and if so how would I overwrite one hash with the other?

Thanks again

Craig
