The OpenDialog works a bit like the GenericDialog with respect to macro
recording: It records the values specified by the user when run
interactively and fills in the values from the last parameter of IJ.run()
when run in macro mode.

So if you call

        java -jar ij.jar -eval 'run("My Plugin", "save=[C:\\ding\\dong.txt]");'

things should work as expected. The key by which the value is referenced
is constructed from the OpenDialog's title. If in doubt, just fire up the
recorder and click through one run of your plugin.

Ciao,
Johannes
