In the wake of the new OS/API Unix initiative, it occurred to Unigram.X to ask how close to Unix System V.4 it really is. They were told that Sun Microsystems Inc, followed by Unix System Laboratories Inc come closest to having all the work done necessary to conform to the 1,170 APIs. Unix Labs figures it’s at least 75% of the way there. Between 25 and 30 of the application programming interfaces are new to it and another 25 to 30 need modification. This means that System V.4 followers like Unisys Corp and NCR Corp aren’t too far off the mark. Of the big name companies that are part of the initiative Hewlett-Packard Co and IBM Corp are reputed to have the most work to do. However, there are suggestions floating around that IBM has been burning the midnight oil trying to move closer to compliance; Hewlett-Packard Co is said to be concerned about the same thing – and probably doing something about.
