In the not so far past, I spent a lot of my time working with and configuring z/OS or MVS mainframes. Over time, I managed to collect a serious collection of useful MVS-commands. Most of these commands can just be found in the forests of IBM documentation but the keyword in my previous sentence is “useful”. I found it, even as a person who was working for years in z/OS environments always difficult to get the right command for a certain action. The lack of examples and over-theoretical explanations made it, at least for me, not very accessible.
Tersing files can be compared to tarring, zipping, rarring files on the x86 platform. It allows you to store a file or multiple files (members) in an archive.

Transferring normal datasets over FTP through other platforms from z/OS can be challenging an this article should provide some help.
