I had a wordprocessor that I used with my Apple II that had features I've never seen anywhere else. I particularly remember -- and still miss -- using variables that could be filled in at print time. If you put the right code into a document you planned to use as a form, whenever you printed it the code would halt the printout, ring the bell, and put your prompt on the screen. Something like "What interest rate?" You'd key it in, hit return, and the document would resume printing. But the ol' daisy wheel printer sounded like a battlefield.
As long as we are into stories about having to walk 20 miles to school -- uphill in both directions -- I wrote a form generator for a mortgage company that printed from their mainframe with some of the data filled in, but the form had to be designed so you could put it in a typewriter and fill in stuff not in the computer. The form had to go into a Selectric and line up without any manual adjustment. Every box had to line up perfectly.
I did that about 15 years ago as a one shot deal. I met someone a few years ago who worked at the company, and they were still using it.
