I have a 3D associative array.

array[string][string][string];

I want to retrieve all values at a particular 2nd index, say “hello”;

array[i]["hello"][k];

I tried using,

foreach(array[i,,k])
    $display("%d",array[i]["hello"][k]);

and also,

foreach(array[i])
foreach(array[,,k])
$display("%d",array[i]["hello"][k]);

Both didnt work. Any suggestions?? Is it possible??

Hi,

Just try this way, It will work.

foreach(array[i,j,k])
    $display("%d",array[i]["hello"][k]);

But in foreach just check for existence of element. If the element doesnot exists , it will return default value.

Hi Anudeep,

This approach will loop through unnecessary values of j right? Anyway to overcome it.

As you mentioned, some of the elements may not exists. I am looking for a way to constrain values of i and k to provide only valid indices. Any suggestions on how this can be achieved, are welcome.

Thank you

Ya, that’s why I mentioned you to have exists check, so that values which are not written or does not exists are not going to be displayed.
