The debugger option "Running until the current line" means run the program from the start until the currently selected line in the program is reached. A breakpoint on the other hand allows for greater flexibility in determining when to stop because you can have as many breakpoints as you want. A condition can be used at a breakpoint to test whether the program should stop or continue.

But you must clear a breakpoint when you are no longer interested in it. If you are sure you just want to go to the current line once, then "run until the current line" is more convenient.
