Dear monks greetings to all.Again I need a help from you .I am trying call a module(create) which will create two text files from there I call another module(difference) to find the difference between those two text files. unfortunately my code exits after printing the text files for the first time.If I run the code second time it will print the results.Every time i have to run the code twice to see the result.Do i have to wait for some time till the file gets created? I tried this but that didn't work.Please help me

sub create
{

open(FILE, "C:/Users/jeyakuma/Desktop/shipping project/input/input.txt
+");  

 open HTML1,">C:/Users/jeyakuma/Desktop/shipping project/url processin
+g/competitors_in_url.txt";       
while(<FILE>)
    {                   
   chomp;
   $url=$_;
   foreach ($url)
    {
    
    
do 'C:/Users/jeyakuma/Desktop/perl/xpathconfiguration.pl';
&domain_check();
 $x="$competitor.html";
 print HTML1 "$x\n";
 
 

}
}

open HTML2,">C:/Users/jeyakuma/Desktop/shipping project/url processing
+/competitors_in_directory.txt"; 
opendir(DIR, "C:/Users/jeyakuma/Desktop/shipping project/database");
@files = grep(/\.html$/,readdir(DIR));


foreach $file (@files) 
{
   print HTML2"$file\n";
 
}

}


do 'C:/Users/jeyakuma/Desktop/perl/tescm.pl';
    &difference();

Both modules are individually working fine
