Enes,

If I run the attached version of your code, I can write out an array smaller 
than the variable to the depth variable. In this case, I see the values I 
expect, as well as the fill values.

Here's a snippet of what I see when I run "ncdump resources\\xyz_grid.nc":

 depth =
  10, 10, 10, 10, 10, 10, 10, 10, 10, 10, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _,
  10, 10, 10, 10, 10, 10, 10, 10, 10, 10, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,
    _, _, _, _, _, _,


If that's not what you see when you compile and run this code, then there may 
indeed be a problem with the CDL conversion from Panoply.
