 Perhaps I am ignorant or something but what exactly is the problem?
 You want to use CARP but something goes wrong clearly; but it's not
 clear to me what goes wrong. I have to admit that I never played
 with Carp and dont know it's details at all; so that might be a
 part of the reason I dont understand.
 If you want proper help, please be more clear about your problem.
