Ah, lo the mellow suggestion! I'm about to join with too. It would be
quite handy, especially for some of us who were using the TIGER _a lot_
in the past, and are using it _a lot_ in the present, and shall use it,
with the sweet permission of providence _a lot_ in the future.

Meantime, though, this is how I solve this problem, so it perhaps could
help others too...

I have both .exe versions 1.4x and 1.2.3 in folder "There" which is
sub-folder of the folder "GPG" (with GPG installed in and with the
working current gpg.exe). Via a .bat file I copy/rename one of the
versions I need into GPG folder, so it becomes gpg.exe. I call the .bat
file with just Win+R (yep, we talk about a Windows now), then typing in
"14" (for version 1.4x) or "12" (for version 1.2.3) and then hitting the
<enter>. It's a pretty quick switch and not very inconvenient. I use
similar "strategy" for a switch between diverse .conf files of mine.

If this is not clear enough I might send copies of my .bat files with
more instructions.

It's easy to do in Linux too, using simple shell scripts, instead the
batch ones.

And, in honor of TIGER192, I'll out of courtesy sign this missive using
this fancy and noble algo. (-: (I switch now to "conf2" .bat.)

OK, so you're a Ph.D. Just don't touch anything.
