What would the following display in scheme?

Question

I have tried this expression on a few (online) scheme interpreters/parsers and sometimes get different answers. For the following expression:

(display "okkk") \; "ok;" ;"ok"

What would it display and/or return? Why? For example:

• Are \ acceptable outside of an s-expression, and do they escape the next character?
• How is a string interpreted outside an expression, or is that invalid?

Answer 1

That probably depends on what Scheme syntax your implementation may support.

One might for example expect:

(display "okkk")    -> displays okkk
\;                  -> error: unbound variable
"ok;"               -> displays nothing, but returns the string
;"ok"               -> end of line comment
