DSPOSRLS: Display Operating System Release

One of the surprisingly non-inuitive parts of the IBM i is that there is no easy way to identify what OS release your machine is on. Well, not if you don’t have enough authority to use DSPPTF.

A common approach is to use DSPDTAARA QSS1MRI which works, but isn’t officially supported. So this approach could stop working at any point and without notice.

The officially supported method is to use the QSZRTVPR (Retrieve Product Information) API. So I did.

DSPOSRLS is a simple command that retrieves and displays the current OS release level. I have posted the source on GitHub so feel free to browse or download it from there.
