var xxx = ....
is local to whatever script contains it.
xxx = ....
is global.

it's supposed to switch to load DATA in that case, I think, and explicitly
show the data.

right -- mod1 is global.
Easier, probably to use:
var modTxt = "echo Copying model data...;mod1 = getProperty('extractModel',
'all');echo;"
Also, I'm not seeing the point of the 1-second timeout for that dupMod2()
business, but if you are planning to do that, I would use jmolScriptWait,
not jmolScript. Then you know it's been executed.
function dupMod2() {

OK, I need to unpack that:
I like the Javscript \ end-of-line continuator here...
function dupMod2() {
var modelTxt = "" + jmolGetPropertyAsString("extractModel", "all");
var scpt = "\
var i = {*}.atomIndex.max + 1;\
var t = {*}.atomIndex.min;\
select within(branch, {atomIndex = i}, {atomIndex=t});\
var x = {selected}.size;\
var y={*}.size;\
var z = y - x;\
if (y > 40 || z != 0){\
echo This feature is limited to a single model with|fewer than
40 atoms.;\
delay 3;echo;\
} else{\
var sz = 3;\
if (y > 4){sz = 4};\
if (y > 10){sz = 5};\
if (y > 30){sz = 7};\
set appendNew false;\
select *;translateSelected {...@sz @sz 0};\
load APPEND '@mod1';\
reset mod1;\
hover off;\
}";
mepsData = false;
jmolScript(scpt);
doUFF(1);
setTimeout("lnkSwitch()", 1000);
}
OK, there's a bug in saving the state from
load APPEND '@x'
load '@x' works just fine, but not with the append. OK. Jmol bug.
