Hi Miguel,

The intention is that RasMol's restrict command applies to all graphics
representations.  The documentation was written when there were only a
handful of representations used by RasMol, and (of course) it was rarely
updated as new representations were subsequently added.

There may be exceptions in existing RasMol/Chime implementations; perhaps
dot surfaces, Chime's solid surfaces, distance monitors, hydrogen bonds,
disulphide bridges, atom labels, etc...  However these should be
considered bugs (perhaps quirks or features) of a particular RasMol script
interpreter.  Script writers shouldn't rely on "restrict none" leaving
anything behind, and future versions may "fix" any anomalies that
currently exist.

If JMol supports more representations than RasMol and/or Chime, these
should ideally also be turned off by the restrict command.  In theory,
"restrict none" should be a portable way for a RasMol/Chime/JMol script
to reset the "display list" independent of any additional functionality
that may be added in future.


I hope this explains the intend or prescribed behaviour of "restrict"
if not any particular implementation.
