I want to write a subroutine for working out what to do and then returning.

Before you jump on the “A subroutine that returns is a function LOL!” bandwagon, I want the return to be executed as it were in the function body calling the subroutine, as though I’ve got a preprocessor to do the substitution, because otherwise this codebase is going to get unwieldy really fast, and returning the return value of a function seems kludgy.

Will vb (sorry I can’t be more specific about what version- I’m writing formulas for an embedded system, our API docs are “it runs vb”) let me do that or fall in a heap?

    It’s not. Tail-calls are a common practice that work just fine.

    They are much preferable than having a function that cannot ever be called unless you want to return its value.
