That makes sense :). I will try to use it if my code reviewer approves :)

A final query on my question. As i want to print only r[0], is there a way to set the array @r to only r[0] during interface_control call

. I mean like this 

push (@r, $r[0])

[download]

I know inside interface_control sub, i can set this, but interface_control can call from outside set this value ?
