elseif fail==1
  disp('You lose')
end
How would I display all the letters the to the user, so they can see what letters they already guessed? Like if I guess an E, and there is no E, I want the program to show that I guessed E. And continue to do that for every guess, and list all the letters I've guessed.
And how do I get my words to be not be case sensitive? :[

Hello,
I modify my 'hangman.txt' at first line :
Signature
chair
calculator
window
picture
browser
phone
book
table
glass
Note that 'signature' becomes 'Signature'
clear 
clc
fid = fopen('hangman.txt','r');
if fid < 0,    error('Cannot open file');    end
data = textscan(fid,'%s');
data = data{1};
fclose(fid); 
index = ceil(rand * numel(data));
word = lower(data{index});
masked = word; 
masked(~isspace(masked)) = '*';
complete = 0;
wrong=0;
letter_guessed = '';
while complete == 0
  clc;
  %fprintf('Word : %s\n',masked);
  fprintf('Letter guessed : %s\n',letter_guessed);
  letter = char(input('Guess a letter : ','s'));
  stat = findstr(word,letter);
  fprintf('letters used so far\n',letter);
  if ~isempty(stat)
      masked(stat) = letter; 
      letter_guessed = strcat(letter_guessed,letter);
  elseif ~isequal(word,letter)
      wrong=wrong+1; 
  end
  if isempty(findstr(masked,'*'))
      complete = 1;
      fail=0;
  end
  if wrong==6
      complete=1;
      fail=1;
  end    
end
if fail==0
  clc; fprintf('You win, the word is : %s\n',masked);
elseif fail==1
  disp('You lose')
end
