AIX Support for the X/Open UNIX95 Specification

The AIX operating system is designed to support the X/Open UNIX95 Specification for portability of UNIX-based operating systems. Many new interfaces, and some current ones, have been added or enhanced to meet this specification. AIX 4.3 is even more open and portable for applications.

At the same time, compatibility with previous AIX releases is preserved. This is accomplished by the creation of a new environment variable, which can be used to set the system environment on a per-system, per-user, or per-process basis.

To determine the proper way to develop a UNIX95-portable application, you may need to refer to the X/Open UNIX95 Specification, which can be obtained on a CD-ROM by ordering the printed copy of AIX Version 4.3 Commands Reference, order number SBOF-1877, or by ordering Go Solo: How to Implement and Go Solo with the Single Unix Specification, order number SR28-5705, a book which includes the X/Open UNIX95 Specification on a CD-ROM.
