Laurel, Maryland-based Century Computing Inc has released TAE Plus version 5.3, a software development environment providing development tools for building graphical user interfaces and management tools, which control the application’s user interface at run-time. Although targeted at application developers and graphic artists, users don’t need to know X Window or Motif, the company claims. It is available now for Sun Microsystems Inc workstations, and versions for Hewlett-Packard Co, IBM Corp and Silicon Graphics Inc will follow. A one-user licence is priced at $2,250, and the price is $11,200 for 15.
