Detailsnext statement is equivalent to the function call
_next(). The return value is the void object of type
DOM_NULL.for, repeat, and while loops, the next
statement interrupts the current step of the loop. In for statements, the loop variable is
incremented and execution continues at the beginning of the loop.
Similarly, the control conditions at the beginning of a while loop and in the
until clause of a repeat loop are verified, before
execution continues at the beginning of the loop.for, repeat, and while loops, the next
statement has no effect._next is a function of the system kernel.
Example
1In the following for loop, any step with even
i is skipped:
>> for i from 1 to 5 do
if testtype(i, Type::Even) then next end_if;
print(i)
end_for:
1
3
5
In the following repeat loop, all steps with odd
i are skipped:
>> i := 0:
repeat
i := i + 1;
if testtype(i, Type::Odd) then next end_if;
print(i)
until i >= 5 end_repeat:
2
4
>> delete i:
