hi,
please note, that VMD by itself assumes that the number of atoms
in a system (or molecule in vmdspeak) does not change.
the operations
you describe are done with the psfgen plugin, so please have a look
at the psfgen documentation.
as for atomselect, it is explained in the vmd user's guide
that this command generates a new "proc" with a unique name
and returns the name to it. for more details, please read the
documentation first.
cheers,
axel.
