<DIV><FONT face=Arial size=2>As someone pointed out recently, assigning a string
to another string only copies 4 bytes, no matter how big the string is.
Only the memory location is copied unless the 2 references to the string go out
of scope, in which case the string is copied in it's entirety. The Copy
command, however, will copy each byte of the string to a new memory
location.</FONT></DIV>
