I blur the lines between coding and documentation. My first doc job was for a compiler vendor using an early flavor of XML. The edits (the program had a CSS and allowed variables, so one set of 'docs' was applicable to a 1/2 dozen products) were done with emacs. I issued 12,000 pages that year. I then 'translated' WordPerfect docs into FrameMaker and did 3,500 pages one year. About 500 were 'original' but that word has a slew of meanings. At other firm, one 3 day project took a 350 page Word manual and converted that into Frame. I used keystroke commands to do the formatting (mouse is too slow for large projects). At the same CAD company, I did multiple revisions of 1,500 to 2,000 page manuals. As I also did the production work including making the graphics right, I have produced at least 36,000 pages. Let me see, 50 lines/page, 36,000 pages, that is 1.8E6 lines. OK I guess I made the top group.
