Hewlett-Packard Co HP NewWave object oriented desktop applications environment is beginning to look like a runaway winner with the news yesterday that AT&T Co has followed NCR Corp and Data General Corp in taking a licence to the software, while Canon Inc has joined forces with Hewlett to develop Japanese versions for Unix, MS-DOS and OS/2. NewWave runs on top of Microsoft Windows and is designed to make it easier for users to move and update information among different applications and to schedule routine tasks to be done automatically by the computer. AT&T, which did not disclose financial terms, plans to use the NewWave desktop as a component of some of its networked computing systems. NCR will be incorporating NewWave into the forthcoming NCR Co-operation office-automation system based on its Open, Co-operative Computing Architecture; Data General will use it in its Distributed Applications Architecture and Comprehensive Electronic Office. Hewlett says that more than 80 independent software developers are working on applications for use with NewWave, one of the key inspirations behind the formation of the Object Management Group, created to apply object-oriented tech niques to establish a common applications environment to improve interoperability of hardware and software from different vendors.
