Since you're obviously using a Unix shell you might be interested in

$ paste a.txt b.txt

as a simpler (though non-awk) solution.

Exactly right Janis =) Really just an exercise for me in wondering:

'How does paste do that any how?'

Now I know. I do wish Windows had a better *native* toolkit for
these sorts of things. The real issue I have is a lack of printf
from the command line in Windows. Awk (paste too) makes these sorts
jobs trivial...

Well, what shall I say to people that want to do such things
but adhere to the Windows platform?

You can of course install Cygwin to have access to the tools.

Myself I got a clear preference once I saw and worked on a
Unix system. And early access to books like Kernighan, Pike:
"The UNIX Programming Environment" solidifies that. (Still
worth reading for newbies, I think.)

The real issue I have is a lack of printf
from the command line in Windows.

This is of course a Unix standard command. And if you can
install some prominent Unix shell (or have it through Cygwin)
you get it even as shell built-in.

Awk (paste too) makes these sorts jobs trivial...

(It's so amazing what you can do with the Unix tool chest!)

Why not use WSL? (Windows Subsystem for Linux) where you get
a real Linux shell and can run Linux binaries?

Or even busybox for Windows, my personal/portable favorite:

<https://frippery.org/busybox/>

Now imagine for instance an older individual, owns a business,
has invested allot of money into their tech, even has a small server.

Now suggest you want to install 3rd party software...

For me its non-issue, but for some it is. The inverse is true as well:
Wine (Win Emulation) can never one up Win API.

When in Rome, do as the Romans do.
