Brothers Keeper produced all these reports as RTF in the case of the Ancestor Charts and TXT in the case of the Lists.
These files were edited, manipulated and formatted by processing with MS-EXCEL97 & MS-WORD97. Each has its strengths and I use whatever tool will produce what I desire.
Both produce HTML files. These are usually suffixed with ".TXT" during processing so I can use MS-Word to remove all the surplus tag information. That reduces the file size to manageable levels.
