If you can, get a copy of KNOPPIX (Linux), and burn it to a CD.
Now boot that CD (it will be "live") and now you can use it to
format the hard drives, over write them, etc. It is a good tool
to have for diagnosing a machine or find out what all it actually
has.
Or, you could tell it to instal

True, but there are lot's of reasons for not wanting to port your 31-bit C/C++
to 64 bit.
One example is when you are using XPLINK-31 with C/C++ and have a bunch of
XPLINK assembler that calls system services/macros that require 31-bit
parameters. Being able to use pointers to C/C++ data d
In my prior response I had not taken into account that you can execute an HLASM

There are “shredding” programs out there for sale which you can boot from a
CD/DVD or USB stick which can wipe (with varying degrees of security depending
on how paranoid you are) any disk. Try search argument “hard drive wipe
software”.

That's Interesting Michael.
Did you see any cases where the Cobol compiler generated unrolled loops of MVCs
(like 4 each iteration)? I've seen that in cases with C/C++, but I don't
remember the conditions. It's really wild how they do it as I recall. It
may have to do with the settings of
I don't know if this is the case here, but it is possible to write a
program to run in addressing mode 64 but use 32 bit instructions so it
works inside the 4GB address range.

No cases of loops of more than one MVC.
And to answer someone else's post: both work areas were aligned (they were
COBOL "01" levels). I think they're fullword aligned.
If anyone wants to try this test, my complete program is:

identification division.

What are you trying to ask? How wide are your data?
In general, if you run AMODE64 then you need to ensure that all 64 bits of your
base and index registers are valid.

MVCL has to check for overlap, possibly before starting any data move

The MVC vs. MVCL considerations are discussed as FAQ #1 in the (excellent) IBM

Reading through the release notes (the "what's new") of the LLVM-Clang based
C/C++ compiler for z/OS I see support for 32-bit programs and XPLINK32 linkage.
Now I have to admit that I not followed all news closely but I even have a hard
time googling this. I thought there is 24-,31- and 64-bit s

Personally I'd remove the drive and use a physical destruction method on it.
Without the drive the laptop is useless. If doubly paranoid you could pull the
memory too.

That's what I've done with old HDDs - remove platters from casing, scratch
and bend them out of shape, and put platters into different bins heading
to land-fill
5lb Sledge hammer is my preferred choice

Most SSDs that I've seen are plugged in to anchor and connect to
them, with the other end with a screw into a threaded hole to
keep them in place.
So you can pull those and smash them. If you have "high"
amperage, say, 50A at 250V, connect them to that flip the switch
and I hope you can stand

Questions:
1. What is the exact model?
2. Does it have an OS on it? Which one?
3. Does it boot?
4. Does it have a CD-ROM drive? If not, do you have an external CD-ROM drive?
5. Do you have a USB flash drive?
6. Is this for personal use, vs. business?
Reason for the questions:

I find that MVCL does exactly what I want for unequal lengths. A lot of times I
want a zero pad, and that's automatic. I've never run into a use case for an
unequal length move with no pad.
What I would like are:
