How not repeat the main loop, if other options are selected?

Hello! I'm building a program, where I need to have the while true, so that until the user clicks exit, the program ends.

And that part I managed to do!

My problem is that there is a part of the program where the user is asked to input things in the command window, meanwhile, I believe the ''menu b'' turns invisible, but it remains there.

When the user has input everything in the command window, I introduce a new menu (''menu c''), but the program first displays the waitbar that was defined at the beginning, and if I click on a button in c, that '' invisible menu b'' will appear.

I don't want to introduce break command, because I don't want to get out of the loop, I need the loop, because other conditions are defined in it that will be needed later in the program.

What I want is that somehow my loop does not repeat itself when another menu is introduced and that menu b closes completely when the user is told to type in the command window, in order not to interrupt the flow of the code.

It´s a little complex what I´m asking, but if you could help me it would be really amazing! I wanna learn about this so much

Here it´s a shorter version of my program...

It might be some errors when u try to break the loop, but my longer version doesn't:

Hope u understand the problem! Thanks a lot!

clc,clear,close
while true
%Operation of menu a
if a==1
wb= waitbar(0,'Starting program, wait...'); % progress bar
for i = 1:1000
wait bar(i/1000);
end
delete(wb) % progress bar
   b= menu('How do you intend to insert the experimental points?', ...
             'Through a file','Manually','Backspace','Exit');
elseif a==2
      break %Exit the program 
end
if b==1 %Menu operation b

elseif b==2
      a1= sprintf('To advance in the program, press 1: ');
      b1=str2double(input(a1,'s'));
 
     c= menu('Regarding the table values displayed in the Command Window:', ...
              'I confirm the values','I want to reset the values','Exit');

     if c==1
       d= menu('example', ...
              'example','I want to reset the values','Exit');
       if d==3
           break
        end
else if b==4
      break
   
     end
 end
     end
end

The code is hard to read. Please open it inthe editor and apply a standard indentation. Fix bugs like "wait bar". Thanks.

Wow thanks a lot it really solved my problem, it´s working exactly as I wanted!! Wow! Thanks a lot! The wait bar it´s not appearing again, big thanks! So the smart identation is used to fix bugs?

"So the smart identation is used to fix bugs?"

Consistently indented code makes it easier for you to debug your code. It also makes it easier to write your code.

Ahhh, Thank u so much!!

Jan, I want to be able to handle the transitions between menus, and if I return, I want that the previous in the main loop doesn´t appear again.

The description is not really clear. I assume, you want a list of menus to be selected one after the other. Then:

status = 0;
... Starting the code
while true
    if status == 0
        b = menu('How do you intend to insert the experimental points?', ...
                 'Through a file','Manually','Backspace','Exit');
        stop = b == 4
        status = 1;
        
    elseif status == 1
        c = menu('Regarding the table values displayed in the Command Window:', ...
                 'I confirm the values','I want to reset the values','Exit');
        stop = c == 3;
        status = 2;

    elseif status == 2
        ... and so on
    end
    
    if stop
        break;
    end
end

Afterwards you have a,b,c,... defined and stop is 1, if the user has selected 'Exit' anywhere.

Sorry if I the description wasn´t clear, but your ideia of use ''standard indentation'', already helped!

Thanks a lot!

How interesting! So if I use command ''status'', will the code run step by step, presenting menus, without going back to the main loop, even if the user inputs something on command window?
