The end of the alphabet


With z/OS 2.1 on the horizon, I thought it would be a good time to take a look back at our history. z/OS was announced October 3, 2000, and available March 30, 2001. So it will have been over 12 years before a new version came out. So in October, 2000, we had a six month release cycle! z/OS base came only on 3480's. The USS Cole was damaged by suicide bombers, and Sony's playstation 2 was released in North America.

It doesn't seem like I've been around for three complete versions of the operating system. It seems like just yesterday I was installing MVS/SP 3.1.0e.

And I still look SO young! ;)

I never liked the name z/OS. Z is always at the bottom of the selection list. AIX is much better in the respect. And zos just doesn't ring. Neither does AIX for that matter. But I do like how the UK guys call it zed OS. Had we done that here in the colonies, I'd probably find it more amusing. MVS is also not an acronym that rolls off your tongue, like CICS or WAS. Mivvess just doesn't cut it. Don't get me started on oz 390.


I guess I was hoping the new version would have a new name, hopefully a clever, catchy name. But then, that's just not how we old farts roll, is it? You know who can name things though? Spies. NSA, CIA. They have great code names for systems, projects and such.

What would you name the next version? Let us know on the forum…

I'll leave you with today's link, which is to a Punch Card creator...

Have fun!

The name z/OS

August 5, 2012 05:12 AM by Edward Jaffe

My peeve with the name z/OS is that it starts with a lowercase letter. When you start a sentence with z/OS, many word processors will flag it as an error or even "correct" it automatically. So annoying...
