next
-- skip a step in a loopnext
interrupts the current step in for
, repeat
, and while
loops. Execution proceeds with
the next step of the loop.

, while
next
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.In 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:
