[CLN-list] how to locate arrays in CLN library

Hi, I'd like to to work with fields of complex numbers of high precision using the CLN library. I can't successfuly allocate the memory using memalloc however. I tired few possibilities, but nothing worked. There is no notice about this topic in manual or in mail discussion, so it seems to be straightforward. But I have no idea how to do it. Thanks for a help Breta Sopik
