Richard, forgive me for just extracting a bit of your interesting mail. I see that the real issue is with the idea of sub-arrays, which have their own sets of keys. You emphatically do not get a list of all the keys of an array with subarrays in it from the ‘put the keys’ action. I modified your handler in just one respect:
on mouseUp put "1" into tA[1] put "2.1" into tA[2][1] put "2.2" into tA[2]["surprise me, Jean"] put 3 into tA[3] put the keys of tA put the keys of tA end mouseUp and I got 3 1 2 So, the “surprise” key wasn’t represented - because it’s a sub-array of tA[2], I suppose. In fact your example is odd in a way, since you use the key [1] for example in the primary array and again in the sub array. These are different keys that just happen to use the same value. This makes my head hurt a bit. So, following on another mail I just sent, I think people can get confused by sub-arrays and what ‘the keys’ actually looks at. More examples needed in the docs, perhaps. Hope this is not seen as wilful misunderstanding - it’s not meant to be!
