Abstract

A system-generated blank hyphen is utilized in addition to operator keyed syllable and required hyphens in I/O typewriter/display systems. The use of the blank hyphen will insure proper hyphen placement, result in hyphenation decisions only having to be made once, improve printed text quality, and provide nonconfusing display.

Blank Hyphen Techniques

A system-generated blank hyphen is utilized in addition to operator keyed syllable and required hyphens in I/O typewriter/display systems. The use of the blank hyphen will insure proper hyphen placement, result in hyphenation decisions only having to be made once, improve printed text quality, and provide nonconfusing display.

Typically, a normal noncoded or syllable hyphen is keyed by the operator for breaking a word at the end of a line and prehyphenating long words. Coded or required hyphens are used on an interword basis in mother-in-law, etc., and telephone numbers. Syllable and required hyphens occurring in a line-end zone during an adjust operation are used as line endings. Outside of the zone during adjust, syllable hyphens are disregarded and not printed, while required hyphens are always printed.

The inherent problems with typical hyphenation techniques are overcome, by requiring that a syllable hyphen be the only hyphen available as a line ending. During adjust scanning on display, syllable hyphens, that would heretofore have been disregarded, are changed to blank hyphens. Also, blank hyphens are changed to syllable and line-end hyphens when occurring within the zone. Required hyphens available as line endings must be followed by a syllable hyphen. Again in this instance, a syllable hyphen will be changed to a blank hyphen when not appearing in the zone.
