Page "IBM AIX" Paragraph 10

Much of the AIX v2 kernel was written in the PL / I programming language, which proved troublesome during the migration to AIX v3.

AIX v2 included full TCP / IP networking, as well as SNA and two networking file systems: NFS, licensed from Sun Microsystems, and Distributed Services ( DS ).

DS had the distinction of being built on top of SNA, and thereby being fully compatible with DS on the IBM midrange AS / 400 and mainframe systems.

For the graphical user interfaces, AIX v2 came with the X10R3 and later the X10R4 and X11 versions of the X Window System from MIT, together with the Athena widget set.

Compilers for Fortran and C were available.

One of the more popular desktop applications was the PageMaker desktop publishing software.
