>From my understanding, a boxed array is boxed or non-boxed entries linked by memory pointer, and needed not allocated in contiguous memory address space. That said, you may write a verb to read a boxed array even memr does not support that natively, likewise for rational and extended integer data types. I have no idea how to map boxed data. -- regards, ==================================================== GPG key 1024D/4434BAB3 2008-08-24 gpg --keyserver subkeys.pgp.net --recv-keys 4434BAB3 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
