I don't recall if OMVS ever included the Korn shell. Haven't paid close enough attention.

The Mortice Kern Toolkit (MKS Toolkit) was also available for Windoze in those days, an excellent "front" on an otherwise non-POSIX system, very similar to what CYGWIN does. I remember requesting MKS TK from my management at the time, but since it's a charge-for product they always wanted more justification than I could muster. Naturally I then landed on CYGWIN which was somewhat of a toy until around 2005.

I was delighted to see MKS Toolkit as a significant part of OMVS because I had seen and used it in the Microsoft world and it worked well there.

Never seen "Kern" apart from "Mortice", so I took "kern shell" to be a typo for "korn shell".

How does Kern shell compare with Bourne shell and POSIX shell?

A quick Google search for "Kern shell" returns mostly pages about
psychology or thermal engineering.
Obvious typo. Was it funny?

More than I care to know about heat exchangers.

https://en.wikipedia.org/wiki/KornShell

And I doubt that I mistyped.  I copied "Kern shell" with mouse from
an earlier ply and pasted directly into the query string.

And there seems to be a passing reference in an IBM page:
