                     11: sets the system's idea of the highest location used by the program
                     12: to addr____.  Locations greater than addr____ and below the stack pointer
                     13: are not swapped and are thus liable to unexpected modification.
                     14: .sp
                     15: An argument of 0 is taken to mean 16K bytes.
                     16: If the argument is higher than the stack pointer the
                     17: entire user core area is swapped.
                     18: .sp
                     19: When a program begins execution via exec____
                     20: the break is set at the
                     21: highest location defined by the program
                     22: and data storage areas.
                     23: Ordinarily, therefore, only programs with growing
                     24: data areas need to use break_____.
