No. These are determined in the loading code and no where else. What people
do sometimes is load more than you need, then only DISPLAY the ones you
want.

Embedded scripts are run after loading, not before. It's an interesting idea
to provide some sort of load functionality within the file, but to date we
don't have that.

There's Jmol script, Jmol math, and Jmol selection syntax. Generally @{ }
sets off math. { } sets off either coordinates or selection, depending upon
the context. What is "C"?
