How do I get started learning S/370 Assembler?
There are many ways to proceed, but probably the most practical way
is to grab Volker Bandke's Turnkey MVS system which comes with the
free IFOX00 assembler as well as lots of other goodies. Once you
have Hercules and the Turnkey system installed (Volker's Turnkey
distro will do both), you can begin assembling and running your own
S/370 assembler programs.
VBB Note: The original Turnkey system is a bit dated now. Juergen Winkelmann
has worked very hard to provide a more current package with many improvements.
It can be found at his website. He uses

Not that MVS38j is the _only_ way to go. There are other S/370
systems in the public domain, such as VM, VSE, TSS, and so forth.
But by far, you'll probably have an easier time with the Turnkey
approach. It's a well supported distribution with lots of
Simply reading the tutorial should help you get started, but you'll
get more out of the tutorial if you are able to experiment in your
own MVS38j environment.
This tutorial will not cover how to install Volker's Turnkey system,
execute jobs, or teach JCL. If you have questions on these topics
please feel free to ask in the turnkey-mvs or hercules-s370asm groups.
