Hi,
  Thanks for the response to my previous post (see below)!  I THOUGHT that 
might be the case however when I change the script, nothing results.  It's a 
bit of a puzzle.  As soon as I get to this loop, the program stops.  When I 
check it with the script editor, the "zoom scale" is highlighted in red and 
prompts me with an "invalid argument" comment.  When I change this to "zoom 
$scale", the code passes muster but still doesn't do anything.  
  I have jmol-11.9.7 running on a macbook pro using 10.6.1, if that matters.  
In advance, thanks!



-----current code for zoom that doesn't work-----
for (var j=1; j<20; j=j+1)
   var scale=5*j;
   zoom scale;
   write image 800 600 @{"movie" + ("0000"+j)[-3][0] + ".jpg"};     
end for
-----------or---------
for (var j=1; j<20; j=j+1)
   var scale=5*j;
   zoom $scale;
   write image 800 600 @{"movie" + ("0000"+j)[-3][0] + ".jpg"};     
end for
----------------------

------Previous response----
in the math itself you just use variables names. $xx would be an identifier for 
a drawn object or isosurface and would not be appropriate in that context. 




for (var j=1; j<20; j=j+1)
   var scale=5*j;
   zoom scale;
   write image 800 600 @{"movie" + ("0000"+j)[-3][0] + ".jpg"};     
end for

Hi,
  I've been trying to make this work but the program doesn't seem to do 
anything when I run it.  What I'm trying to do is write a series of images that 
zoom into a structure.  Suggestions?
-------------------------------
for (var j=1; j<20; j=j+1)
   scale=5*$j;
   zoom $scale;
   write image 800 600 @{"movie" + ("0000"+j)[-3][0] + ".jpg"};     
end for
-----------------------------



In advance, thanks!
