I have two programs working on win32 system program 1: Create a TXT File and write data 
$FH = FileHandle::Rollback->new("> $filepath") or die "cannot open fil
+ehandle: $!";
select($FH);
for my $i(0..$#{$temp_array1[0]})
{
my $stringline=join(" ",@{$temp_array1[0]->[$i]});
print("$stringline \n");
}
$FH->commit;

program2 : read TXT files and write them in one bin file 
  opendir(my $FILELIST,"temp")|| die $_; 
   
   while(my $filename=readdir($FILELIST))
   {
            my @temp_ref=grep{($_->{SecID}.substr($_->{Date},0,4).subs
+tr($_->{Date},5,2).substr($_->{Date},8,2).".TXT") eq $filename}@Task_
+list;
            my $TaskRef=$temp_ref[0];
            

         
        if((-e-r $TXTfilepath.$filename)&&defined($TaskRef))
        {
             &writebin($TaskRef)                     
         }
}

usually, I run program2 when program1 is finished, but now it is a need to run both on the same time,which means we need interprocess comunication between these two programs. I dont want to connect them in threads way, It is not stable on windows Xp . Is there any easy way to send task from program1 to program2 ,and let program2 waiting for task? thanks
