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;
