The product itself was for both MVS and VM/CMS - https://www.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ss...

But possibly MVS customers outnumbered VM/CMS ones to the point that you rarely or never worked with any of the later

What a blast from the past, thanks. From memory VM/CMS use was mostly internal and most of my customers at least were on MVS. VM was mighty fine.
