How to convert JS function to ZP format?

[Vasar]

Hello, help me please to convert this function for ZP execution, is it possible?

function FindZero(F) { with (F) {
var j, X, XV, HV, LV, Fn = EX1.value
var Lo = userIn(Min1), Hi = userIn(Max1)
X = Lo ; LV = eval(Fn)
X = Hi ; HV = eval(Fn)
if ((LV*HV)>=0) { Ans1.value="Bad bounds" ; return }
for (j=0; j<40; j++) {
X = (Hi+Lo)/2 ; XV = eval(Fn) ; if (XV==0) break
if ((XV*LV)<0) { Hi = X ; HV = XV } else { Lo = X ; LV = XV }
}
Ans1.value="X = "+SigFigExp((Hi+Lo)/2, 8) } }

Here is example what it does http://www.merlyn.demon.co.uk/js-demos.htm#FZ
