Maidenhead, Berkshire-based Tetra Ltd says Chameleon 2000, its Unix-based financial and accounting software, now supports JSB Computer Systems Ltd’s Multiview Mascot windowing interface. According to Tetra, Chameleon users will now be able to view multiple Windows and Unix applications and perform several different tasks simultaneously on Unix-based character terminals. It also enables Chameleon 2000’s accounting modules to interoperate with a range of Windows applications, including spreadsheets, word processing and graphics. To do this, Mascot uses Dynamic Data Exchange links, which extract data directly from the accounting system and transfer it a spreadsheet, such as Microsoft Corp’s Excel. Cut and paste options for text and graphics are also available for both systems. In the meantime, Tetra has announced two joint UK marketing agreements with Sequent Computer Systems Ltd and Motorola Computer Group Ltd to put Chameleon 2000 up on Sequent’s Symmetry 2000 and Motorola’s 8000 machines.
