I've been using break very often in Pascal loops for 25 years since 
Delphi 2. Also continue.

My code is littered with:

repeat

  do_something;

  if x then BREAK;

  if y then CONTINUE;

  do_something_else;

  Application.ProcessMessages;

  if key_clicked then EXIT;

until 0<>0;

ProcessMessages allows the user to stop the loop if it is running out of 
control.
