1972SPELL at Stanford's AI Lab: it reads your file, and for each word not in its dictionary it gives the page, the line and the word. Stanford.
See also: An NSA paper, 'A Program for Correcting Spelling Errors', which flags any word not in its list (undated copy, c.1960).
“When the spelling checker encounters a word that isn't in the dictionary, it will type the page number, the line on which the word was found and the word itself.”
Checking words against a list is probably older still: an undated NSA paper describes it around 1960.
Someone opened the dated document itself. The source.
