[tlaplus] Re: action never enabled

[Jones Martins <jonesmvc@xxxxxxxxx>]

Hello,

From your example, it seems Spec should be: Init /\ [][Next]_vars, assuming vars is already a tuple/sequence. I am not sure if that solves your problem, though.

TLA+ newbie here with what is probably a newbie-ish question.  I'll describe it abstractly with actions A and B.   My spec has the form:

Next == A \/ B

Spec == Init /\ []Next_<<vars>>

When I run TLC I get a warning "B is never enabled".  If I change the ordering in Next to:

Next == B \/ A

I get the warning "A is never enabled."  Am I missing something obvious about disjunction?

Thanks for any insights in advance!
