In some scripts i've seen variables defined with asterixes (*variable*). Is this just for the purpose of readability or will those variables be treated as special types (pointers?) Unfortunately i haven't found that much about this. So could please somebody give me a hint, where to find more? In "Teach Yourself Scheme in Fixnum Days" or "SIOD: Scheme in One Defun" i haven't seen an explicit explanation. (maybe my old eyes....?) Michael ------------------------ Yahoo!
