Re: [tlaplus] Defining multiple possible actions in one line

[jack malkovick <sillymouse333@xxxxxxxxx>]

An update to my silly problem. The issue was that x was added at a later time and I was using a view... unfortunately I did not update the view also :)

Yes. I did try that on my spec (that is not as simple as the above), so the error is somewhere else :(

Thanks for the answer. I'll keep digging...

Have you tried

Next == \E p \in Possibilities : Increase(p)

Another beginner question. Let's say I have something like

VARIABLE v

Increase(x) == v' = v + x

Possibilities == {1, 2, 3}

And I would like to define something like

Next == Increase(1) \/ Increase(2) \/ Increase(3)

but using something like p \in Possibilites. I've tried all kinds of stuff but a silly subtle error makes TLA to generate only one action instead of 3.
