Thanks Ben. Glad to hear it works well enough. The test I wanted was
just the "device,DECOMPOSED=0,RETAIN=2" you use, and could have been
done in the VM or normal version. The reasons the VM even comes into
the question at all is that, with command-line IDL, you can just
instruct the user to use a DEVICE setting which works in their IDL
startup file, whereas in the IDLVM, no startup file is ever consulted,
so you must compile in a best-guess DEVICE call.
