ExactTarget SSJS: Landing Page - limiting amount of subscribers from a Subscribers.Retrieve() function?

Question

I would like to limit the amount of subscribers retrieved with the following function:

var myList = List.Init(listExternalKey);
var subsArray = myList.Subscribers.Retrieve();

When used on a large list (~8000), the Landing Page times out when using this function.

Is there any way to count the items in the array as it's being retrieved and stop after 200? I don't need the rest of the subscribers if it's not possible to carry on retrieving the rest of them.

The documentation only refers to filtering by specific subscribers, but I don't know which subscribers are in there - and only want x amount of them anyways even if I did. http://help.exacttarget.com/en/documentation/exacttarget/content/server_side_javascript/server_side_javascript_syntax_guide/core_library_server_side_javascript_functions/list_server_side_javascript_functions/

Any help would be much appreciated!

Retrieve will returns the data in the form of Array. Use length keyword to check the array size and initialized the count in the for loop.

Example:

var myList = List.Init(listExternalKey); var subsArray = myList.Subscribers.Retrieve(); for(var i=0; subsArray.length>i&&200>i; i++) { Write(subsArray[i].EmailAddress +'<br/>')
}
