Dick Tracy has stepped off the newspaper comics page and onto the streets of Dallas, where police are using mobile data terminals to write and file reports from the field, reports a management information services journal.

Reminiscent of Tracy's two-way wrist radio, notes MIS Week, the units have been installed in 250 patrol cars for two-way communications between headquarters and the field.The use in Dallas reflects the growth of mobile data communications, from annual sales of $37 million in 1987 to projected sales of $ll4 million in 1991, a threefold increase.
