Much of the computational aspect of my PhD was written in BCPL[0], it's nice to see it's still alive and running.
Greybeard story time:
I learned BCPL when competing in a CoNeutron[1][2][3] competition. My player was written in Pascal but I kept getting errors. Eventually I tracked down a compiler bug, produced a 20 line program that provoked it, and submitted it to the Computer Lab. I got back a standard "We'll look into it, but it's probably a bug in your program."
About 30 minutes later I got another email, this one said: "Wow, it is a compiler bug ... congratulations! But it won't get fixed."
So I learned BCPL, transliterated the CoNeutron player code into it, and it immediately ran about 10 times faster and became effectively unbeatable. My player even beat David Seal[4][5]'s player running on then new ARM processors ... details of which were confidential, and never fully revealed.
Fun times.
=================
[0] Other bits were written in ForTran, zed line editor, and batch-control, all running on an IBM3084Q with Phoenix as the OS.
[1] It was intended to be a Neutron competition, but the rules were incorrectly explained.
I would be surprised if someone, somewhere, didn't still have a copy of what would nowadays be considered to be an absurdly small amount of data. If they do, I wouldn't be surprised if they read HN.

BCPL was great. Cambridge Lisp was written in BCPL, and I found BCPL really pleasant to work in.

Digressing, but I wonder if any copies of Phoenix/MVS survive, and if so, whether it could be made to run under Hercules
