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

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?
