You probably don't need the 0+, but you might be surprised to look at the
characteristics of those parameters:
mycall = function(app,msg,msg2, id) {
alert(app + " " + msg + " " + msg2 + " id=" + id + " id+1=" + (id + 1) +
" id/2=" + (id/2) + " typeof id=" + (typeof id) + " className=" +
id.__CLASS_NAME__)
}
*jmolApplet0_object script 1 started load $caffeine; id=-3 id+1=-2
id/2=-1.5 typeof id=object className=Integer*
Cool, huh?
