I've been messing around with a language that I summarize as:
ALOE = Scheme + Smalltalk + Types
Boids implementation:

Super cool to see a new Scheme on DOS.

Aw, no call-with-current-continuation?

How much does that really get used?
pmcgoron a day ago
As an escape continuation, more than you'd expect. (Exception handlers, early return.) Full continuations are rarer, but I use them for doing error recovery.

Fantastic to see the DOS Lisp scene revived again. Back in the day there was PC-Scheme from Texas Instruments, which I believe was R3RS-compliant.

Gambit-C has also been around since '88 and can compile to fairly portable C.
Probably been a decade since I tried compiling it for DOS, but I believe getting it up and running shouldn't be difficult.

Gambit-C 3.0 binaries are available at:
https://gambitscheme.org/3.0/gc30-dj.zip
(for DOS/DJGPP)
The other versions from https://gambitscheme.org/3.0/ are Windows or MacOS Classic binaries.
Needs a 386+ CPU, though.

What I remember from back in the day was XLISP.

That's going way back, and was portable enough to be used on a variety of operating systems. There was a package of it for the HP Integral!
An early version of Xlisp was used as the basis for Autolisp, but Autolisp wasn't updated to track Xlisp's capabilities. It's kinda like how Commodore BASIC was a nerfed version of Microsoft BASIC that Commodore licensed back in the 1970s and then never updated since to track later BASIC versions, just added a few commands here and there to support later Commodore machines.
