never write code on no sleep.
that code sample should be :
timers= (function () {
var timers = [];
var id=0;
timer=function (f,t) {
timers.push({func:f, interval:t, id:id++});
return id;
}
return timers;
})
runScript("env.js");
runScript("program.js");
ev=getEvents();
while (!programHasQuit()) {
handleEvents(timers,ev);
}
