I recently came across a very interesting e-book about the Word Perfect Corporation:

Back in the DOS days, Word Perfect was absolutely the best word processor, in my opinion. It seemed that every detail of the program — installation disks, layout of the menus on the function keys, Reveal Codes, printer drivers, etc. etc. — was well thought out and thoroughly tested, with quality in mind.
I had Word Perfect 5.0 for DOS with a Daisy Wheel printer. One of my favorite things about Word Perfect was that you could easily make changes to your printer definition profile. I purchased a multi-lingual printwheel and put the codes into Word Perfect to print all of the special Spanish characters — upper and lower case accented, tilde, umlaut; as well as the upside down question mark and exclamation point.
Printing an accented lower-case letter was easy; you would print the letter, do a backspace, then print the accent. However, it was more complicated with an accented upper-case letter: you would print the letter, do a backspace, change the size of a line, do a reverse line feed, print the accent, do a forward line feed, and change the size of a line back to the normal size. It was really cool to watch the daisy wheel printer do all of that for accented upper-case letters!
The only problem I encountered with this process was with an upper-case N with a tilde above it. Somehow the tilde would lock the printer or do other weird things to it.
I really loved doing Word Perfect 5.0 on my original IBM PC with 640K of RAM and a 20 meg hard drive. It ran like a champ, which it was in every way.
