I tried your code but it would not compile, complaining about a wrong lvalue assignment. Turns out to be the assignment in the while statement. && has higher precedence then =, so the = will failt. Solution: surroung "object = mjtNextObjectIMP ## object(mjtForeachEnumerator ## object, mjtNextObjectSEL ## object)" with another pair of ()'s A bit late, but some people might run into the same problem as I did.
