The BREAK command terminates the looping of a statement block executed by DO, FOR, REPEAT or WHILE commands. A BREAK command only exits from the statement block in which it is invoked. To exit from nested loop commands separate BREAK commands for each loop must be used.

BREAK

FOR(I=1;I<10;I=I+2) IF(A(I)<B(I)) BREAK

(see also REPEAT-BREAK example in 5.3)
