Produced this result with the SL plugin:
var idexport = stringIDToTypeID( "export" );
var desc387 = new ActionDescriptor();
var idusing = stringIDToTypeID( "using" );
var desc388 = new ActionDescriptor();
var iddirectory = stringIDToTypeID( "directory" );
desc388.putPath( iddirectory, new File( "~/Desktop" ) );
