I don't see the need for two programs from what you show, but assuming your design is correct fork will let you exec B 

defined( my $foo = fork) or die $!;
$foo or exec '/path/to/B', @parms;

That is enough if you are certain that B will run longer than the remainder of A. Otherwise you must prevent B from going zombie.
