Does anyone have a copy of the VM Library (aka. Waterloo tape) for VM/370
Release 5 or earlier?
We have a copy of the VM Library tape for VM/370 Rel. 6, but several mods
that were on earlier tapes were removed at Release 6 due to space
considerations for fitting onto a single 9-track reel tape.
COMMON, the IBM midrange (System i, iSeries and AS/400) user group
(www.common.org), which is very similar to SHARE, began a similar
exercise about 5 years ago. They started distributing hand-outs on CDs,
instead of paper copies, to reduce costs and save a tree. Many people

was not until well into the evolution of MVT that BSL was first used for
much of TSO and some other utilities.
C++ is a low-level language comparable to C, being only slightly
higher-level than assembler or machine language. So, there is no
technical reason why parts of an OS kernel (even the z/OS nucleus) could
not be written in C++.
It is well-documented that when IBM transitioned the AS/400 from
C++ was intentionally developed by grafting on OO concepts to C, while
still keeping the language at essentially the same level. In other
words, you can still do pretty much the same kinds of low-level things
in C++ that you could do in C. The main difference is, you can also use
the OO
