Oh, the single underline was used in 'fry' vocab.
I consider using a double underline to represent anonymous variables...

These are nice!
Thanks, Jhon. I'll use them.
My code was heavy and confused about what was "anonymous variable".
So I change it as follow:
SYMBOL: *anonymouse-var-no*
:
Some small simplifications using ``counter`` and ``slots>tuple``:
```
SYMBOL: *anonymouse-var-no* 0 *anonymouse-var-no* set-global
: reset-anonymouse-var-no ( -- ) 0 *anonymouse-var-no* set-global ;
: generate-anonymouse-var ( -- var-symbol )
[
*anonymouse-var-no* counter

Thank you.
My program needs to make a symbol every time it finds '_'.
It became as follows:
SYMBOL: *anonymouse-var-no* 0 *anonymouse-var-no* set-global
: reset-anonymouse-var-no
Yep, you can also use the syntax for it:
<< { "foo "bar" "baz" } [ create-word-in define-symbol ] each >>

Oh, I was able to do it as follows:
[ "a-symbol" "factor-logica" create-word define-symbol ] with-compilation-unit

Hello all,
How do I code to generate symbols at runtime? "define-symbol" seems to work
only at compile time.
I'm writing an embedded language that runs on Factor with the capabilities of
a subset of Prolog. To achieve the anonymous variable functionality, I want to
generate as many symbols as
