TGR Software Inc, a Brazilian developer and marketer of micro-to-mainframe development tools and personal computer access security software, has moved its international headquarters to Atlanta from Sao Paulo, Brazil: the company began marketing its products to companies in Brazil in 1985, but believes that the potential for its products in the US is such that it needs to have its international headquarters there; multinational customers include American Express, Chase Manhattan, Coca-Cola, Dow Chemical, Electronic Data Systems, General Electric, IBM and Johnson & Johnson; the company was founded by Brit Philip Lay, now its president, with a Brazilian and an American; its Tiger Connection enables the user to develop and implement micro-to-mainframe applications without developing custom mainframe programs, and SCUA Plus is a complete systems administration package for MS-DOS designed to deliver streamlined operation while protecting the organisation from information loss and data theft.
