in reply to Parallel Processing

Then launch DoThis.exe in the background. How this works depends on the operating system. perlport talks a bit about this (if I remember correctly), and Super Search will surely find some discussions about it.

    Thanks every one.

    I found a simple solution that meets my requirement. What I did was added "START" inside the system command
    for 1..5{
system("START DoThis.exe");
}

      No need for START. This will do the trick on Windows: 

      for (1..5) {
  system(1, "DoThis.exe");
}

      See perlport.

        meh. 

        for (1..5) {
   system('start DoThis.exe');
}

        vs 

        my @pids;
for (1..5) {
   push @pids, system(1, "DoThis.exe");
}

waitpid($_, 0) for @pids;

        Maybe zombies don't matter and you can reduce the latter to something akin to the former, but we haven't been told that.

        Then again, I would want to know if the children died, and using start hides that data.

    Thanks for the quick response. FYI Script runs in Windows.
