You seem to be misunderstanting the diference between call multiple process from batch and spawning child processes from a parent (Independent Processes vs. Process with Child).

What you described can be best done with creating child processes. You need to learn about Inter Process Communication (IPC). Buy Programming Perl from O'Reilley and read from pg 343 through end of chapter very carefully.

Good luck,
