At work I had an old version of Adobe Acrobat Pro, version 9, which I used combined with some Actionscript and batch actions to fill in form fields using a csv file and finally outputting to one pdf file per record.
Is this functionality still supported in Acrobat XI Pro Win ESD?
I would think it would be, but I just thought I would check with some other people and find out as the features listed on the website do not mention that specifically.
