function roll(speedB) {
  if (document.form.col1.value=="V") {
     document.form.a1.value=Math.floor(Math.random()*9) +0  ;
  }
  if (document.form.col2.value=="V") {
   document.form.a2.value=Math.floor(Math.random()*9)+0  ;
  }
  if (document.form.col3.value=="V") {
   document.form.a3.value=Math.floor(Math.random()*9)+0  ;
  }
   timerid=setTimeout("roll("+speedB+")",speedB);
}
function stop(col) {
  if ( col==1) if(document.form.col1.value!=" "){
   document.form.col1.value=" ";i++;}
  if ( col== 2) if(document.form.col2.value!=" "){
   document.form.col2.value=" ";i++;}
  if ( col==3) if(document.form.col3.value!=" "){

}
