        ls=document.isn.txt.value; 
        if (ls==""){  
                alert("I'm sorry.  I don't find any text pasted into the text window");  
        } 
        else{  
                htmlPar();  
        } 
}

function htmlPar(){ 
        document.isn.txt.value="Working......."; 
        pos=ls.indexOf(dq); 
        pos1=ls.indexOf(sq); 
        if ((pos>-1)&&(pos1>-1)){  
                reWrt();  
        }

                ls=ls.substring(0,lc)+" "+ls.substring(lc+1,ls.length);
