I have the following temporal formula:
y'= 0 \/ y ~0 -> y-1
Which I hope says that the next value of y is zero or y-1 if y is not zero.
However, when I put this as a property in TLC, I get the error:
Was expecting ===== or more module body, encountered '~' in Properties at line 1 and token 'y'.
Obviously it's not happy with the ~ (equally unhappy with \lnot), but I'm not sure how to proceed from here!
