Hi Andrea,

   Thank you very much, as your code is pretty good for our 
scenario, just one request, the above is a part of our main code 
where we have many such sub code and all of our sub code use the 
container array(std.container.array) rather than standard 
array(std.array), so can you please guide me on how to implement 
the same code using the container array.

From,
Vino.B.
