Well, it's "function" as in logic rather than computing, but I suppose 
the analogy is OK.

What you need for the sentence you have in mind is abstraction with 
"nu". What you want to refer to is _the event of_ John running through 
the store. Using the programming analogy, "nu" turns the brivla into a 
function returning a sumti.

One way of saying this would be:

le nu la djan. bajra klama fo le zarci cu rinka zo'e poi se lumci mi
[the event (John run-go with-route the store)] cause (something 
such-that is-cleaned by-me)

or avoiding "zo'e":

le nu la djan. bajra klama fo le zarci cu mukti le nu mi lumci ri
[the event (John run-go with-route the store)] motivate [the event (I 
clean it)]

(Note we can't use "rinka" here, since John's running can't physically 
cause me to clean the store.)

You can also use modals, e.g.

la djan. bajra veka'a le zarci .isemu'ibo mi lumci ri
(John run via-route the store) and-as-a-motivational-effect (I clean it)
