[ferret_users] array dims; plotting the last row of a netcdf array

[Patrick McGuire <mcguire@xxxxxxxxxxxxxxxxxxx>]

Dear Ferret Users
   This is probably a very simple question to answer. I am trying to 
figure out how to plot a line plot of the last row of a netcdf 2D array.

if I knew beforehand the maximum row number (i.e. MAXJ) then I could do 
something like:

plot/vs/line/vlimits=-0.05:0.85/hlimits='$hlimits' xc,w[j=MAXJ]*DIC[j=MAXJ]

This size is unknown unless the user looks at the array manually.

Is there a way to get the size of the array? like sizeof() or dims() in 
other languages? Or is there a better way to do what I want to do?
