   Hi John,
Don't worry, this was almost right!  You can think of the chain ID
as part of the residue specification, so that you need to put it
on each residue number or range of residue numbers:

select :32-42.o,44-49.o

rep sphere  

which is somewhat more of a pain to type, unfortunately.  The reason is  
theoretically there could be another chain that doesn't have an ID, so  
numbers not together with a specification of chain O would specify  
in the no-ID chain.

There are a few more examples in


I hope this helps,
