jmolGetProperty is indeed very powerful. It taps into a set of array data
for the model. Mostly it is good for atom-based information. I don't know
that it gets you these read-only variables. The easiest way to get them
from JavaScript is using jmolEvaluate:

var myJSvar = jmolEvaluate("_spinning")

for example. This function does the same as the "print' command, but
delivers the result directly back to the JavaScript.
