Alternative to "continue"

Hello, is there any alternative to that continue?

You could wrap everything in an if

for .......
  if m == 0
      % Code you want to run
  else
      fprintf('O Username deve .............
  end
end

That doesn't use a continue.

And in this situation?

Thanks

Yes it does... If I remove the continue, the program will exit the while and go to another step....

[Walter Roberson]

The code you display here has no way to exit the while loop, because nothing changes x . We must suspect that after the if m ~= 0 that you have more code that might change x, with the general structure

while x == true
  some code here
  if m ~= 0
     display error
     continue;
 end
 some more code here
end

You would change that to

while x == true
  some code here
  if m ~= 0
     display error
 else
   some more code here
 end
end

1. Why do you ask?
2. Programming languages are efficient. This means that if there is an instruction to do something, there's not going to be another one to do the exact same thing.
3. Maybe there is an alternative but that would depend on the for loop that encloses the piece of code you've shown, so you've not even shown enough code to answer your question.
