Hallo,
Writing RTF's eh? This is something I have done lots of, and it's quite easy, although I cheat a bit - why do something difficult when there's an easy way out?
Firstly I create a document in Word. Set up all the headers, footers, page layout etc. Also include some recognisable text in all the fonts you want to use. Then save it as RTF.
Edit it in a text editor and copy all the lines before your recognisable text into an Access routine called WriteRTFHead (which you pass the file Id of you open file), turning each line (with sensible line breaks) into a simple Print # Statement.
Then do the same for the lines after your recognisable text, into a routine called WriteRTFTail.
You can then Open a file for writing, call WriteRTFHead, write your data, then call WriteRTFTail, close the file and you have created you RTF file.
Here's my mdlRTF module:

'and ysnCompleteReportFile should be called as the last thing before the file is closed.
'strFormatRTFString should be used whenever data not containing RTF codes is written to
'the file to ensure it is valid RTF, especially data input by the user.

This additionally sets up Header and Footer data, held in a table, tblLayoutData. This has a text primary key fields of:
txtLayoutName: a name for each layout (allows multiple layouts)
txtPageName: First, Odd or Even
txtVerticalPositionName: Top or Bottom (for Header or Footer)
txtHorizontalPositionName: Left, Centre or Right
The data fields are
txtLayoutItemText1,
txtLayoutItemText2 and
txtLayoutItemText3 which are the lines of text in the Header/Footer item. In these Items you can use ^d, ^t, ^p and ^q, for Date (of generation), Time (of generation), Page Number, Total Pages respectively.
If you set up a table with these fields, the program should work. Any header and footer items not found are just set as blank.
The function strFormatRTFString returns the supplied text string, formatted for the RTF file. This should be used for user input data (unless it contains RTF codes).
I hope this is some help. If the Header/Footer bits are too tricky/confused then you can always omit them.
Also, the MS Rich Text Format (RTF) Specification, Product Support Services, Application Note 1/94 GC0165 has all the basics and is quite readable. It also has a highly amusing chapter title, Conventions of an RTF Reader. Ho Ho. Those zany cats at Microsoft.
