Since you posted this on the L, I assume that you want to use SAS.

I am not aware of any easy way to read a PDF (and, I am assuming that your PDFs were created using Acrobat or one of the converter programs such as ODS) directly with SAS. In the past when I have needed to work with data stored in a PDF, I have used one of the on-line tools that create a text file from the PDF. If you have Adobe Acrobat (not just the reader), you could save your PDF as a text file. Otherwise, there are commercial programs such as PDF Converter for Windows 7. Some of these are able to do a conversion on all the PDFs in a folder. Once you converted you 1 plus 10 pdfs, you could read them as text strings with SAS and , say, merge the matching lines and check to see if the strings are identical. Of course, you could use a file comparison program to do this also.

Hello all How can I compare pdf files? One pdf file (pdf1) is a large file and there are other 10 pdf files which make up to form PDF1 (ie., pdf1+pdf2+pdf3+...pdf10). I need to compare these two pdfs. How can I do that? Thanks JOhn
