Hi All
First, Thank you to Marco to getting me to this point!
I need to take a PDF on the IFS, convert it to a Base64 and return it back
through a web service.
I am getting the Base64 and looks correct but when it is sent back to the
service it is adding weird characters to the beginning of the field.
Variable length info? The field is NOT defined as a variable length field.
When converting back to a PDF it fails because of the garbage characters.
What the H.....eck am I doing wrong?
