column extraction in NCL

Hi,

I am using the command asciiread to access a file from unix which has 35
rows and 99 columns. I want to extract the fifth columns but I failed to do
it. I am afraid there is a limitation for the dimension of the file. Also,
some columns contain the word "NA", when I assign the columns like
this, IN_value = IN_Array(:,2), it will automatically omit the column so it
will extract the wrong column. What should I do?

Thanks and regards,
Maggie
