Create single report generated from multiple pdf files

I need to generate a report to extract information from multiple pdf files.

To get a report from a single pdf this script works fine tested from the console:

var docfile = this.documentFileName;

var rep = new Report();

rep.size = 1.2;

rep.color = color.blue;

rep.writeText (docfile + "\r\n");

rep.open("My Report")

Not sure how to generate a single report listing document file names from multiple pdf files?

Any assistance in help creating this report will be most appreciated - thank you.

Update:

I have modified the script to be an action script - there are separate reports generated for each document file name instead of a single report with multiple document file names listed in the one report.

If any one can help that would be great.

var docfile = event.target.documentFileName;

var rep = new Report();

rep.size = 1.2;

rep.color = color.blue;

rep.writeText (docfile + "\r\n");

rep.open("My Report");

console.println(docfile);
