Help: setting array properties

Hi.

I have an array name region it has a couple of properties. "code", "name", "value"

I want to store this array in an indexed object called regions.

I would then like to access the object by referring to its sub property name

regions[1].code
regions[1].name
regions[1].value

I think I am doing something wrong.

I can set an array region.code, region.name and region.value but I can not set the regions values

regions[1].code = "abc"
regions[1].name ="alphabet"
regions[1].value =26

note: region is singular and regions is plural(many)

Can someone outline the variable definition and construct so I can access this information. Happy to replace the index field with the code value.

Thanks in advance

Still having difficulty in constructing this array

regions[index].code;
regions[index].nm;
regions[index].value;

or

regions[index],[region];

or
var region:Array("code","nm","value");
index=1;

regions[index] [code]= "A";
regions[index] [nm]= "abc";
regions[index] [code]= "123";
