Hi IF,
I think this is what you want. You were right about the issue -- you were
consing onto the history list but then immediately throwing away the result
because it wasn't modifying the original history value.

I can get the code that follows to run, but the chatbot never replies. I
surmise this is because lists are not mutable.
With the background I have the most obvious way forward would be to use an
array instead of a list, but that does not strike me as the best approach

Hi,
Presumably you are using 'head' to get the first element of a list.
However, there is no function 'head' for lists.
see: https://docs.racket-lang.org/reference/pairs.html
Try using 'first' and 'rest' instead of 'head' and 'tail'.
