@christoph-hart thanks a lot

What is better:
for (var i = 0; i < 200; i++){
or
for (i = 0; i < 200; i++){
and why i cant use:
for (local i = 0; i < 200; i++){

What is the scope of "i" on that bucles?
Thanks

Is there anyway call to more than one function in multithread.
I mean launch functions in a separate parallel execution threads.
I need:
function a(){
b();//run(b());
c();//run(c());
}

function b(){
playnote....
}
function c(){
playnote....
}
