    Abstract: In an abbreviated typing system, in which a data processor (20) transfers abbreviations typed on the keyboard (10) into longer, full words, display of words in exceptional forms is efficiently achieved. Such special forms include initial capitalized, all capitalized, initial italics, all italics and combinations of these. The sequence for capitalization is typical. When the first letter only of the abbreviation is capitalized, decision (260) (FIG. 9) of the processor (20) results in action (264), by which only the first character of the full word is capitalized. When more than one letter is capitalized, decision (260) results in action (262) by which all characters of the full word are capitalized. Underlining is effected by underlining all characters when the first letter of the abbreviation is underlined and all of the characters plus the space following the word when more than one letter of the abbreviation is underlined.

  • Patent number: 4359286
    Abstract: A method of, and system for, increasing the number of characters available to be printed with a single print element. If a printer is printing from storage and the character being presented to the printer does not match the print element in use, a determination is made as to whether the character is in fact available on the element. If so, the character is caused to be printed. If not, a determination is made as to whether the presented character can be constructed from characters existing on the print element. If so, construction is caused to occur to avoid a print element change. If, however, the presented character does not exist on the print element and cannot be constructed from characters that do exist on the print element, a requirement for a print element change is signalled. Following a change, printing will continue with the new print element as long as characters are available, or can be constructed from available characters.

  • Patent number: 4205922
    Abstract: A system for handling multiple printer font requirements during playout of a plurality of sequentially stored text columns in a side-by-side format. A line from one column is printed on a print line, the carrier is caused to escape, and any corresponding line from a succeeding column is printed on the same line. Printing and escapement continue until all corresponding lines from each column are printed on the same print line prior to causing a printer carrier return. During playout within a column, or from column to column, printer font requirements stored with the text are used to determine subsequent system events. If one of the columns, or a portion thereof, is to be printed in a different type style or language, the system will signal a need for a font change, stop the playout and await an indication that a font change has been made.
