Now that the Apple Computer Macintosh is finding its way onto the desktops of corporate America and Europe, software developers are rushing to endorse it, and Lotus Development Corp has come up with a major revamp of its Jazz integrated program, calling the new version Modern Jazz – for users who want the benefits of integrated software without having to sacrifice power. It combines worksheet, graphics, database, forms, word processing and communications – and a command language unique among Macintosh software. It imports and exports 1-2-3, Symphony, Microsoft SYLK and text files, needs 1Mb and two floppies and costs $395, this quarter.
