I was reminded of an editor I used when an engineering tech at DEC back
in the 70's [ TECO ]. There are references to a 32 bit Linux version
being available [1]. I would like to travel down memory lane.

I've a collection of machines with 32 &/or 64 bit Debian installed.
How do I check which flavor an operable system is running?
TIA

Problems solved - Thank you very much.
I thought that I had installed 64 bit on this machine. I had.
*BUT*, by default I boot 32 bit. Means I can experiment with TECO ;}
Also, exploring inxi manpage should be fruitful.

You can run 32-bit executables on 64-bit platforms, so in principle no
need to care which variant you have.

But there's an olde say to the effect of "exceptions prove the rule."

In this case https://almy.us/teco.html states:

Now, TECO is available for Linux. Many changes to the UNIX version of TECOC have > been made to bring this implementation up to snuff. The gzipped

archive contains

the executable, documentation (some specific for Linux) and support files, and
the source files necessary to recompile if you find it necessary.

Linux TECO distribution (https://almy.us/files/tecoclinux0398.tar.gz 367k)
-- built for 32-bit Linux. If you have a 64-bit distribution you will need
to add 32-bit support or recompile from source.

As I stated earlier today my primary system is 32 bit. So no problem :}

But you can not run 64 bit executables on a 32 bit platform.

Yep ;}
That wasn't my "problem".
https://almy.us/teco.html states:

Linux TECO distribution (367k) -- built for 32-bit Linux. If you have a 64-bit
distribution you will need to add 32-bit support or recompile from source.

I was focusing on "... you will need to add 32-bit support ...".
I had always thought that a 64 bit system could always run 32 bit
software. In any case my primary system turned out to be 32 bit.

Thank you for your time.

Yes and no. Within the x86 world:

1) All current 64-bit CPUs can run 32-bit applications and operating
systems.

2) Normally 64-bit kernels can run 32-bit applications (you might be
able to disable this but itrCOd be an odd choice in a general-purpose
OS).

3) You will still need a certain amount of library support (ld.so and
libc at a minimum) to run dynamically linked 32-bit executables, and
thatrCOs the bit that may be missing in any given install.

The CPU-level support for 32-bit operating systems may be withdrawn in
the future; see:

Note that this means that the 32b kernels cannot be booted. 32b
applications are still possible with X86S; no X86S CPU has been
announced. The paper says itself that it is just there to solicit
feedback, so maybe X86S will never reach hardware.

Looking at the page, it's interesting that Intel uses "IA32e" in the
table about "Supported and unsupported modes in X86S", a name that
they have replaced with "Intel 64" elsewhere (including in this
document) once it was obvious that IA-64 (aka Itanium) was not going
to take over the world.

Statically linked binaries should work without that, but you need
to install 32 bit library packages to run 32 bit dynamically linked
binaries on 64 bit systems.

You can also then compile 32 bit binaries on 64 bit Debian by using
the right options to GCC.
