Inserting filename and page numbers into multiple PDF files?

Question

Have since seen this thread, BUT still interested in the syntax of the code
to insert filename and page # into multiple files:
http://forums.adobe.com/thread/951925?tstart=0
Good Evening (GMT!)
I have approx 100 PDFs with one or two pages in each, they are English translations
of Russian language test certificates and the formatting/feel of the originals is lost in
the translations. The only real link between the two sources is the "_RUS" and "_ENG"
filename suffixes and the common leading filenames otherwise. Thus I need to maintain
a record of the filename in any page I print off, should there be a need to refer back to
the original if the translation is open to artistic licence.
I have a script (below) that happily adds a page x/y and filename into the active file,
what I would like is to be able to do this insertion into multiple files as defined by a
portfolio or a selection via a select files dialogue box
I am quite out of my depth now as my past skirmishes with JavaScript have set
cookies and tweaked a few other browser doodads in webauthoring
Any help most appreciated on this one...
Kind Regards

NB the filename inserted may be corrupted as a result of my last tweakings
will sort that one out ASAP....

Putting this in a batch file within the automation function of Acrobat
delivers the goods, I need to investigate the formatting of the output to
get them to line up, have taken the middle ground and gone for a central
position for the page x/y text...... some lines are redundant
