The following program displays all the perfect numbers up
to 1000:
EXPORT PERFECTNUMS()
BEGIN
LOCAL k;
FOR k FROM 2 TO 1000 DO
IF ISPERFECT(k) THEN
MSGBOX(k+" is perfect, press OK");
END;
END;
END;
REPEAT Syntax: REPEAT commands UNTIL test;
Repeats the sequence of commands until test is true (not
0).
The example below prompts for a positive value for SIDES,
modifying an earlier program in this chapter:
EXPORT SIDES;
EXPORT GETSIDES()
BEGIN
REPEAT
INPUT(SIDES,"Die Sides","N = ","Enter
num sides",2);
UNTIL SIDES>0;
END;
BREAK Syntax: BREAK(n)
Exits from loops by breaking out of n loop levels.
Execution picks up with the first statement after the loop.
With no argument, exits from a single loop.
CONTINUE Syntax: CONTINUE
Transfers execution to the start of the next iteration of a
loop.
