Cool, this works with a few minor issues:
1) the "set preserveState false" command, when placed in front of the
"getproperty" line wipes out the x variable.
2) when I hit the button that triggers the "x=getproperty("fileContents")"
command the 1st time, the alert is empty; and it's only the second time that
the alert pops up the file contents. Bob's example at
http://chemapps.stolaf.edu/jmol/docs/examples-11/s.htm does not have this
problem.
For reference this is the jmolscript that I used to load a file:
load_script = "zap; load ?; echo waitmessage;select not solvent;
boundbox{selected} on; echo get_bound; set hideNavigationPoint false; set
perspectiveDepth off; set axesMode 0; set axes 3; set frank on; select all;
color chain; center selected; spacefill off; set background black; wireframe
off; select protein; cartoon; select ligand; wireframe 100;color boundbox
red;echo load_success;";
jmolScript(load_script);
load_script="hi = getproperty('fileContents');";
jmolScript(load_script);
alert(jmolEvaluate("hi"))
alert("hi2");

Just make sure you work within the Jmol scripting system. getPropertyAsString()
bypasses that, as does jmolEvaluate(). You must create a Jmol variable
containing the file contents using the script, then you can access that
variable from JavaScript any time.
The following should work:
load "?"
set preserveState false
x = getproperty("fileContents")
then LATER
javascript:alert(jmolEvaluate("x"))
jmolScript("reset variables")
or anything else that you want to do with that file contents.
I advise also using preserveState false or at least the reset variables just
because otherwise you could have some VERY large states that involve encoding
the variable "x" being created.

Hmm, the show files command at jena3D does work well for me. I wonder, though,
that since the jmol file was loaded from server side (as opposed to client
side), that you can pass file contents freely to js scripts.
