Uh... is it possible to say Hello World in APL?

Strings, character vectors, are written within single quotes (') and typically the last expression is printed so - 'Hello World' works.

@EssieRivers But what characters will be inside the single quotes?

I'm not sure what you mean. The characters 'h' 'e' 'l' 'l' 'o' ' ' 'w' 'o' 'r' 'l' 'd' will be inside the string 'Hello World'

@EssieRivers Oh. I taught you needed other characters instead.

I see! Nope, ordinary characters do fine

@EssieRivers Hey, long time no see. There was a discussion about tacit.help producing things like {=⍵} when it concievably could detect that = doesn't work monadically. I tried changing the cover for = and the other strictly dyadic functions to not be ambivalent, but somehow that also made =/ fail. Any ideas?

Hi! Let me see...

Great. You can look at what I did here.

Do you remember how it failed, specifically?

(∧ being another one of the strictly dyadic functions.)

Lovely, thanks

I'm afraid I don't know, sorry ^^

I would guess the issue is _o, I can't see anywhere else a simple operand could be called dyadically and I can't imagine how else that issue would occur.

@B.Wilson Yup, there's some lazy binding, but I'm unable to list all the places where that'll happen. It'll certainly happen when the value is required and the name is unquoted.

Beginning soon:
