MATLAB: Use a loop to load .dat files (with matrices) and manipulate them

.datdirloadtxt

Hi, I have some .dat files which include measurements in a matrix form. I want to load them in matlab and in each of them to remove some of the columns.
I am trying something like this but it doesn't work:
nof=10;  % number of files
for i=1:nof
  D=dir('*.dat)
     load (D(i)....) %????
    % remove column
end
Any help?

D = dir('*.dat');
nof = min(10, length(D));
for K = 1:nof
  thisname = D(K).name;
  Indata = load(thisname);
  Indata(:,17) = [];  %delete column 17
  %then what?? Guess I'll save the data
  newname = ['new_' thisname];
  save(newname,'InData')
end
