I have never used it but it may do the trick for you.

If you consider PDF output, FRX2Any will append reports easily.
Good Luck,

Well i cannot merge them, since it will break the file structure in my opinion. I want to generate a multipage TIF document through "print-to-file" method instead of a listener, since the one generated by VFP9 cannot be opened by old viewers ( like Kodak previewer in Win98 ). This report is sent to a very wide audience ( over a thousand daily ), so it is important to be as compatible as possible...
What i do now is generate 2 tif files, and attach them to the mail, but i would prefer to have this in the same file...
