What LB means, is that you should learn to format your code.
You did that with break by indenting it.
Part of formatting is to make it readable.
Taking shortcuts, is considered bad programming.
As you can see below adding curly braces makes it easy to see where the if begins and ends.
1 2 3 4 5 6
if(command == "exit")
{// Begin if
Command 1
Command 2
Command ...
}// End if
Imagine trying to understand the below pseudo code without good formatting.
1 2 3 4 5 6 7
While (true)
if (nottrue)
goto dosomething;
print helloWorld;
if (notdone)
do somethingelse;
print done;
