But what size are the doubles stored on the heap? Say if you have a struct field the contains a boxed double and you need to retrieve it. You just make all objects use a multiple of 16 bytes of memory and waste a word for those that are actually 8 bytes smaller. __Martin _______________________________________________ Lisp Hug - the mailing list for LispWorks users [email protected] http://www.lispworks.com/support/lisp-hug.html
