If you already know about machine-level programming, then probably the
best reference book for 370 machine-level is Principles of Operation.
Be sure to get the right version -- if you aren't using access registers
and all that jazz, then the ESA/370 PrincOps is total overkill.
Similarly, if you aren't using 31-bit addressing and/or the XA I/O
subsystem, then the 370/XA PrincOps is overkill. For standard
programming in, e.g., the VM/SP or VM/HPO environment, S/370 PrincOps is
just fine (GA22-7000).
