were implemented by control sequences; for example, letters were automatically converted to lower case unless they followed a full stop, that is, the "period" character. Output could be printed on a typical line printer in all-capitals — or in upper and lower case using a special ("TN") printer chain — or could be punched as a paper tape which could be printed, in better than line printer quality, on a Flexowriter. A workalike program with some improvements, DORMAT, was developed and used at University College London. Electromechanical paper-tape-based equipment such as the Friden Flexowriter had long been available; the Flexowriter allowed for operations such as repetitive typing of form letters (with a pause for the operator to manually type in the variable information), and when equipped with an auxiliary reader, could perform an early version of "mail merge". Circa 1970 it began to be feasible to apply electronic computers to office automation tasks. IBM's Mag Tape Selectric Typewriter (MT/ST) and later Mag Card Selectric (MCST) were early devices of this kind, which allowed editing, simple revision, and repetitive typing, with a one-line display for editing single lines. The first novel to be written on a word processor, the IBM MT/ST, was Len Deighton's Bomber, published in 1970. Effect on office administration The New York Times, reporting on a 1971 business equipment trade show, said The "buzz word" for this year's show was "word processing", or the use of electronic equipment, such as typewriters; procedures and trained personnel to maximize office efficiency. At the IBM exhibition a girl typed on an electronic typewriter. The copy was received on a magnetic tape cassette which accepted corrections, deletions, and additions and then produced a perfect letter for the boss's signature ... In 1971, a third of all working women in the United States were secretaries, and they could see that word processing would affect their careers. Some manufacturers, according to a Times article, urged that "the concept of 'word processing' could be the answer to Women's Lib advocates' prayers. Word processing will replace the 'traditional' secretary and give women new administrative roles in business and industry." The 1970s word processing concept did not refer merely to equipment, but, explicitly, to the use of equipment for "breaking down secretarial labor into distinct components, with some staff members handling typing exclusively while others supply administrative support. A typical operation would leave most executives without private
