Subject:      Surprise about the observation length

Hi All,

       I have to surprised by seeing this about observation length

I got the following output from the below program.

My question is why it is showing observation length 24( for all 3 vars)
even after the variable X length is reduced to 5 ? or Am I missing
something?

Thanks in advance
Chandu.
