why does stata return . in results after list

[Tara Boyle]

I've got a variable _at1

I want to get the value of _at1 when timevar == 2

I found the value in timevar closes to 2 which is 2.01005

I then wrote

list _at1 if timevar==2.01005

///Yet stata returns:

.

What is wrong?
Of course I can manually look for it, but curious to know what's wrong

Note that part of the answer is that Stata returns nothing, as no observations satisfy the criterion. The period you're seeing is the prompt for the next command, not the output of list.
