Thank you very much for your reply.

Your solution has the advantage that script B.pl even could be on another server than script A.pl. But in this case, I don't need this feature, so the disadvantage of being "expensive" in networking terms outweighs the advantage.

Therefore, I have chosen another solution (see above). Nevertheless, I have voted up your proposition because it surely will work and has an additional interesting feature.
