Line continuation

Is there a specific way to do a line continuation in ZScript?

I know you can write
[VarSet, s, [StrMerge, s, " and", " this", " and", " that", " and", " the kitchin sink"]]
as
[VarSet, s, [StrMerge, s," and",
" this", " and", " that",
" and", " the kitchin sink"]]

but is there a way, without comments, of deliberately showing that a long line has broken, like say \ (backslash) or equivalent?

No, there’s no way of indicating that you’ve used line breaks to organize your code.
