C++26: A Placeholder with No Name

If we're counting only programming languages (and not fill-out forms), Prolog had it in 1971, before ML. ASCII didn't include _ until its 1963 draft, so it's probably somewhere in that time.

I'll guess it's probably Prolog, but maybe Planner (Prolog's predecessor) had it too.

ASCII 1963 was the first version of the standard and it lacked _ https://dl.acm.org/doi/10.1145/366707.367524

The 1965 draft had _ https://dl.acm.org/doi/10.1145/363831.363839

The first standard edition with _ was 1968 https://www.rfc-editor.org/info/rfc20

The 1977 version is also available https://nvlpubs.nist.gov/nistpubs/Legacy/FIPS/fipspub1-2-197...
