How to enter input variable from dialog box into text file?

if true
  % code
prompt={['What is your name?']};
title = 'Name Machine';
answer = inputdlg(prompt, title);
name = answer{1};
fileID = fopen('NameMachineFive.txt', 'w');
fprintf(fileID,['His name is %s.', name]);
fclose(fileID);

Ignore the top 2 lines and that was the original code. It was displaying "His name is " in the text document without the name. Then, dpb helped me out to fix it. Thanks dpb!

Please don't edit away the question -- makes the whole thing useless for anybody else going forward. I suggest re-editing to put back the original as it was.

That you "Accepted" an answer indicates the issue was resolved.

Agreed. My apologies.

I have edited the question again to show the original code (couldn't find out how to remove the if true % code part), the problem, and who helped me.

fprintf(fileID,['His name is %s.', name]);

should be

fprintf(fileID,'His name is %s.', name);

You've put the variable name in a character string with the format string and left no output variable to be printed.

ADDENDUM

Intended to note but forgot--in your script you used title as a variable for the dialog box heading. This aliases the TMW-supplied Matlab function title of the same name so if you want to plot something later and add a plot title you'll get an error.

Avoid using Matlab functions as variable names--admittedly, when still learning it's not always easy to know. That's why the color coding in the Matlab editor is useful amongst other things.

Thank you very much. It worked!

Thank you in addition for the addendum dpb.
