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

Perfect ...

irb(main):001:0> a = { [1, 1] => ["X", "20120501"], [1, 2] => ["X", 
"20120502">
=> {[1, 1]=>["X", "20120501"], [1, 2]=>["X", "20120502"]}
irb(main):002:0> b = { [1, 2] => ["O", "20120403"] }
=> {[1, 2]=>["O", "20120403"]}
irb(main):003:0> a.update(b)
=> {[1, 1]=>["X", "20120501"], [1, 2]=>["O", "20120403"]}
irb(main):004:0> a
=> {[1, 1]=>["X", "20120501"], [1, 2]=>["O", "20120403"]}
irb(main):005:0>

Thanks for your help Martin - much appreciated and so easy in the end. I 
guess that's why people love Ruby.

Cheers

Craig
