Abstract
The typewriter is equipped with the capability to check or verify the spelling of words as they are typed and the typewriter may also upon request from the operator provide candidate words from which the operator may select a word to replace a misspelled word. When a candidate word is selected, the typewriter electronic controls check the spelling of the misspelled word and delimit the zone which contains the erroneous characters. Only the characters that are within this bounded zone are erased from the page and the character which fit within the zone in the new or correctly spelled word are printed, eliminating the need to remove characters which are outside the zone and which are correct in the original word and will be correct in their position in the correctly spelled word.
