It feels like Pascal in Cyrillic. Autotranslation, with a little manual correction, but I can't fix КНЦ (autotranlated to KNC):

  FUNC FACT (N);
     NAME: R;
     1 -> P;
     FOR I FROM 1 TO N ::
        R * I -> R
     ALL
  RES: R
  KNC;

  FOR N FROM 0 TO 6 ::
     ? "FACT(", N, ") = ", FACT(N)
  ALL;

replace cyrillic w/ russian and it'd be ok.

КНЦ = end (конец in russian is end). However, in bulgarian in means 'thread' (as in sewing thread) and it has lots its meaning of end, aside from 'from needle to thread' expression where it means from the tip of the needle to the end of the thread.

Also 'ALL' (и все = it's over/that's all), which should be 'end' as in begin/end in pascal.

The main point still stands - it's Pascal.

Few fixes:

1. "ИМЕНА" is plural, so instead of "NAME:" it's a bit more appropriate to use "NAMES:". Probably should be "VARIABLES" or "VARS" in modern context.

2. You've got few typos mixing "R" and "P". Should be "R" everywhere.

3. Instead of "ALL" you should use "DONE".

4. Instead of "KNC" you should use "END".

So it would look like this:

    FUNC FACT (N);
      NAMES: R;
      1 -> R;
      FOR I FROM 1 TO N ::
        R * I -> R
      DONE
    RES: R
    END;

    FOR N FROM 0 TO 6 ::
      ? "FACT(", N, ") = ", FACT(N)
    DONE;

I would read «КНЦ» as «КОНЕЦ», literally “an end” or “the end” (Russian does not have anything resembling articles). Who needs vowels, anyway.

Also, «ВСЕ» feels like «ВСЁ» in this context, I’d translate that as “that’s all”.

There is also an independent open-source interpreter for 1C language (which is to this day reported to be extensively used in Russian enterprise) implemented in C#. I haven't tried it myself, but just though that it's also worth mentioning here as the project seems to be actively worked on: https://github.com/evilbeaver/onescript

The playground on [demin.ws/rapira](https://demin.ws/rapira/) feels well made.

This is a pretty cool historical artifact.

Does anyone use "native language" programming languages in education or day to day?

1C is widely used in Russia as part of 1C:Enterprise (https://en.wikipedia.org/wiki/1C:Enterprise think sap/abap)

UPD: 1C can be used in both Russian and English. And I'm pretty sure it can be used outside of 1C:Enterprise.

It also has BSL Language Server and IDEA\VSCode extensions.
