The main problem you're running into here is that you're defining the  
world function after you're trying to use it.  When you use functions  
as default values, there is an argument passed to the function that is  
the value of the index and you forgot to return the string value from  
the world function.  Lastly, when you call most code it needs to be  
inside of an event handler, but you can wrap the code inside of a  
bro_init event handler which executes once Bro has completed it's  

I'll include a fixed version of your test script.

function world(i: count): string
return fmt("hello world - index is %d", i);

global a: table[count] of string &default=world;

event bro_init()
         a[1] = "navdeep";
         a[2] = "singh";

         print a[2];
         print a[3];

----script output----
$ ./src/bro test5
hello world - index is 3
