Looks good but as far as I can see it does not allow me to iterate over 
assiociative arrays so I can get the value of a certain key from all 
arrays.

Say I have...

AssocArr1=(key1 value11
           key2 value12)

AssocArr2=(key1 value21
           key2 value22)

So how do I iterate over...

    array=(AssocArr1 AssocArr2)

...so that I get value12 (= AssocArr1[key2]) in the first iteration and 
value22 (= AssocArr2[key2]) in the second?
