Hi,
I tried this at Jess prompt:
(reset)
(assert (a))
(bind ?m (engine mark))
(assert (b))
(engine resetToMark ?m)
(facts)
At the end, fact (b) is still there. Shouldn't it be retracted with
resetToMark?

You're not calling resetToMark; you're providing two arguments (the
symbol resetToMark and the variable ?m) to the engine function,
which are both ignored. You want to say
((engine) resetToMark ?m)
Similarly, you're not calling mark -- you want to say
((engine) mark)
