Export to PDF

Hello,

I would like to export inx file to pdf file using javascript (.jsx). however, when i ran this script using testclient command it gives expected semicolon error.

here is the script...

var my_input = app.scriptArgs.getValue("in");
var my_output = app.scriptArgs.getValue("out");

var myDocument = app.open(File(my_input));

if(app.documents.length != 0){
    app.documents.item(0).exportFile(ExportFormat.pdfType, File(my_input)), app.pdfExportPresets.item("[High Quality Print]"));
}

Would please suggest what wrong in this script?

Thanks,

Shailesh
