The boxes may be any construct in the language including blocks and entire programs. In almost all cases this eliminates the need and use of one of the most common pitfalls in programming: the label and associated go to statement. These are provided in FLEX but they will rarely be used. Former PORTtfAN programmers who convert to ALGOL find that they almost never need to use labels or go top and time spent in debugging gets reduced by a sizable factor. d.
