ABSTRACT:
A stored directory is searched from a display station set to obtain the telephone number of a sought-after name. The arrangement uses the station set keypad to generate signals corresponding to the spelling of the sought-after name. The arrangement adds each entry it receives to previously formed sequence of entries and, for each newly formed sequence, returns to the station set the name and telephone number contained in a directory record having a string of characters that compare to the newly formed sequence. The arrangement also provides means for scrolling through the directory.
