This group's been empty on my machine for a while, I missed this discussion
and could use some help understanding...

I am writing an intelligent chess board in STV to help in some analysis; I set
the initial position of the board with a literal array. I was surprized
the second time I ran the program and, after initialization, got the
old board. Without understanding, I threw in a deep copy and it worked
fine. The documentation on deep copy is recursive "answer a deep
copy of the receiver". I've used lost of pointers and indirection in C;
if someone would help me and tell me what's going on, I will understand!
But I can't understand STV by its external behavior.

Thanks!
