function browser.onclick(){
var nW = window.open("","","width=170,height=200");
nW.moveTo(300,100);
nW.document.write("<script defer>/r"+
"var m=true;/r"+
"function insert.onclick(){/r"+
"if(m){/r"+
"opener.atext.value=btext.value;/rm=false;"+
"}else{/r"+
"opener.atext.value+='/-'+btext.value;/r"+
"}/r}/r"+
"<//script>/r"+
"<input name=btext value=111111 size=10 style='BACKGROUND: #ffffff; BORDER-BOTTOM: #0A3EAE 1px solid; BORDER-LEFT: #0A3EAE 1px solid; BORDER-RIGHT: #0A3EAE 1px solid; BORDER-TOP: #0A3EAE 1px solid'>/r"+
