The term POSIX was originally used as a synonym for IEEE Std 1003.1-1988. A ^^^^^^^^^^^^^^^^^^^^^^^^^^^ preferred term for that standard, POSIX.1, emerged. This maintained the advantages of readability of the symbol ``POSIX'' without being ambiguous with the POSIX family of standards. For a full listing of the project numbers see PASC Standing Document SD11. The name POSIX was suggested by Richard Stallman. ^^^^^^^^^^^^^^^^ http://en.wikipedia.org/wiki/MVS ------ First released in 1974, MVS was later renamed by IBM, first to MVS/XA (eXtended Architecture), next to MVS/ESA (Enterprise Systems Architecture), then to OS/390 when UNIX System Services (USS) ^^^^^^^^^^^^^^^^^^^^ were added, and finally to z/OS when 64-bit support was added on the zSeries models. Its core remains fundamentally the same operating system. By design, programs written for MVS can still run on z/OS without modification. ------ http://www.opengroup.org/openbrand/register/brand3470.htm ------ UNIX 95 Company Name: IBM Corporation Product Name: z/OS V1R2 or later with: Security Server and z/OS V1R2 or later C/C++ Compiler on IBM zSeries Processors that support z/OS Version 1 Release 2 or later ------ And regarding [Guh-NÜ-slash-]Linux, POSIX.1 is basically kernel+[g]libc. regards, alexander. _______________________________________________ gnu-misc-discuss mailing list [email protected] http://lists.gnu.org/mailman/listinfo/gnu-misc-discuss
