| TLC parses the temporal formula, Init is a state predicate and Next is the [1] action that appears within the sub formula [][A]_v.

[1] Although in TLA+ it is OK to write specifications that contain more complex formulas, such as [][A]_v /\ [][B]_w, TLC only accepts temporal formulas that contain a single sub-formula of that form. On 23 Oct 2023, at 11:09, jayaprabhakar k <jayaprabhakar@xxxxxxxxx> wrote:
In TLC we can specify the behavioral spec as a temporal formula spec, and that is typically defined as Spec === Init /\ [][Next]_vars /\ WF_vars(Next) In this case, - How does TLC know Init is the init function? And more specifically, how does it know Init must happen before any Next operation occurs?
- Is it by the order in which they are defined or by convention like if the name is Init etc?
Thanks, JP
