In general, yes.
Thanks for your reply.
Some ranges have value semantics and can be saved simply by
assigning them to a new variable, or passing them to a function.
How can I identify those ranges, or, how can I tell if any
particular range has value semantics ? I didn't read any of this
in the manual - not that I could remember anyways.
Thanks for your help!
