Is this really a question about Adobe Acrobat? Looks like an entirely different product.
Yes, this is a question about the PDF file. It is not accepting line breaks in a valid script. I would like help with creating line breaks to separate lines of an address.
To insert line-breaks you need to use the "\n" or "\r" characters. In VB it would be Chr(10) or Chr(13).
You can use VBA but it is run externally and the accesses the PDF object within VBA. You will get more help in the Acrobat SDK forum that covers the Acrobat SDK and how to use other computer languages to access PDFs files.
It would also be possible to use Unicode strings, hexadecimal values, or octal values.
