[note: this message relates to the experimental prototype "Jmol 10.x" not
the public release Jmol 10.2. See
http://www.stolaf.edu/people/hansonr/jmol/test/proto/new.htm for details.]

This syntax is possible in the prototype only. In 10.2 you can only

measure [atomno] [atomno] [atomno] [atomno]

where there are from 2 to 4 [atomno]s, each an integer.

In 10.x, the measuring and selecting capability is greatly expanded:

e.g.

measure 1.0 20.0 (atomno=1 and model=1) (atomono=30 and model=1)
# measures the distance between these two atoms, provided it is between 1 and 20 angstroms.

Note that (as of yesterday) this works, too, now, because it is specific enough to be obvious what is intended:

measure 1.0 20.0 (atomno=1 and model=1) (atomono=30 and model=3)
# measures the distance between these two atoms, provided it is between 1 and 20 angstroms.


measure all (atomno=1) (atomno=2)
# when there are multiple models, this will measure all atom 1-2 distances at 
once.

measure all 1.1 1.5 (carbon) (oxygen)
# measures all carbon-oxygen distances between 1.1 and 1.5 angstroms

measure all 110.0 120.0 (carbon) (nitrogen) (hydrogen)
# measures all angles fitting this specification (note: right now no connection check is being done)

select atomno=3 and model<3
# just what it says

select molecule=1
# first molecule [i.e. covalently bonded set] (in all models)

select model<3 and molecule<3
# first 2 molecules in the first two models

select within(molecule,iron)
# just what it says

connect (atomno<3 and model<3) (atomno>3)
# just what it says -- connect is only within models, so only one specification is necessary there.



etc.

I use syntax like this:

As far as I know, you cannot use model=1
for selection. The syntax is
  /1
hence
measure 1.0 20.0 (atomno=1 and */1) (atomno=30 and */1) or measure 1.0 20.0 ((atomno=1, atomno=30) and */1)
or have I missed something?
