ABSTRACT:
A data input and processing apparatus as used in a typewriter, having a function of checking the spelling of entered words which are separated by word-separation data such as a space or a period. The apparatus has a device for inhibiting an operation defined by the word-separation data, e.g., a spacing movement to the next word, if the spelling-check device finds a misspelled word. Where there exists at least one numeral and/or symbol preceding or following the entered word, the numeral and/or symbol are ignored in checking the spelling of the entered data. When a misspelled word is found, the entered word is first erased, and then at least one candidate word which replaces the mispelled word is presented to the operator. The apparatus may have a plurality of operation modes including a candidate indication mode for displaying the candidate word, an ignoring mode for ignoring a misspelling alarm, a retyping mode for re-entering a correct word, and a correction mode in which the misspelled word is corrected in part by changing and/or deleting the characters.
