in thread How to call two programs simultaneously from a running program

After forking, we still have to wait/waitpid for the child process to end in order to avoid zombies, unless we employ the double-fork technique.

Instead, try this: system "perl B.pl &"; system "perl C.pl &"

    fork is a somewhat cross platform. system "... &" is rather system dependent. There is no telling what the OP is using of course and there is a fair chance that using & will do the trick for the OP.
