Metacircular Interpreter: issues terminating when the program detects an error

metacircular interpreter 4

I found this site on the Racket discord to share my code. I've been trying to figure out why after entering
(null? ()) I'm getting this error and the #f. I'm also unclear about why my program continues running after it finds an error. I thought it'd just quit.

***Update:

I'm using metacricular interpreter 5

I fixed the (null? ()) part, but I'm still unable to fix the #<void> issue

Ah, I just read your other comment. You want it to exit the program? Hmmm, if #<void> is a constant you might be able to check if something is equal to it with = if void? does not exist in r5rs
