    It's either [IBM *i*](https://en.wikipedia.org/wiki/IBM_i), aka OS/400 or AIX. Can you run `uname -a` (or `oslevel`)? If yes, it's AIX, IBM i apparently has a command named `GO LICPGM ` for this (http://www-01.ibm.com/support/docview.wss?uid=swg21634678). Theoretically, it could even be RHEL 7.2, but this would be a strange way to describe this OS. – Sven Oct 09 '17 at 16:53
  • Appreciate it, trying to determine what I need to do to compile libcurl into functioning DLL on this OS, but there is so much non-specific info out there on iSeries stuff it was tough to determine. – ProfessionalAmateur Oct 09 '17 at 17:04

It is one of the operating systems supported on IBM Power Systems alongside AIX and Linux as well as on IBM PureSystems alongside AIX, Linux and Windows. source

V7R1,2,3 is a sucessor of OS/400.

A fact on the name;

When IBM announced the new Power Systems line of servers on April 2, 2008, they renamed the operating system from i5/OS to IBM i[3] and changed the version identifier format from VxRxMx (Version, Release, Modification, e.g. V6R1M0) to the more standard format (e.g. 6.1).

    The part about IBM having changed this versioning scheme prevented me from outright stating it's OS/400. Most likely it's correct though and this is just a not-yet changed part of the OS. On the other side: AIX is somewhat familiar if you know any Unix type OS (like Linux) - OS/400 is *very* different from what I understand (unfortunately, I've never used any of this stuff). – Sven Oct 09 '17 at 16:56

AIX and OS/400 are two completely different animals. The only significant relation between the two are that they are both developed by IBM.

AIX is IBM's version of UNIX. OS/400 (i5/Os) is not a Unix operating system. It is the successor to IBM's System 36/38, completely different operating system.

OS/400 does have a Unix based shell that can be used to port and run AIX applications, but that is about it.
