A memory typewriter having an editable text stored in the memory together with a full-page correction buffer and individual counters associated with each differentiable word in the text. The combination permits determination and display of the most frequently used words in an edited text in order of descending frequency. Preferably, the combination includes a thesaurus list so that the typist can be altered if a frequently-used word in the display is also present in the thesaurus list. If so, the typist can then call for display of related synonyms by pressing or appropriate key controls and decide which of the synonyms, if any, to enter as replacement for the overused word.

An electronic typewriter having a punctuation checking feature checks each punctuation feature as it is stored in a memory section, against a set of predetermined rules which define punctuation errors in terms of the context of the punctuation mark. If the punctuation mark does not agree with the defined rules, a suitable alarm, such as a visual and/or audible signal is given to the typist. A plurality of algorithms form the basis for sub-routines which a microprocessor can execute to determine if any of the rules are violated. The punctuation of a complete file can be checked by calling out each character in the file, from beginning to end and applying the checking procedure.

Punctuation check feature for an electronic typewriter

A word-processing system or memory typewriter having a list of commonly-confused words together with a definition for each word in the list and associated alternative words and their definitions, all stored in the memory. An audiovisual warning signal is generated upon each entry of a commonly-confused word so that the typist can press key controls to display definitions of the entered word and its alternatives. The list is of general applicability but, where specific ones of the commonly-confused words cause no concern to a particular typist, the controls may be individually modified by that typist to suppress issuance of the warning signal when these specific words are entered thereafter. Preferably, a Dictionary List of properly-spelled words is present in the system and utilized in controlling access to the list of commonly-confused words. When the definition of an alternative word more nearly matches the one desired, the typist's pressing of the usual carrier return key on the typewriter keyboard causes the system to display and/or print the alternative in place of the misused original word (in proper alignment, of course).
