I OCR'd a sizable manuscript written on a pretty shabby portable typewriter. I scanned each page twice, making sure to move the paper between scans. Then I ran both diff (by words, not lines) and spell to smoke out trouble. The word list for a program listing is quite short and easy to generate. (Print a list of all the apparent words and visually eliminate the nonsense.) And a spell check is an easy pipeline of standard utilities. doug
