[tlaplus] Re: Question about prophecy variables

When transcribing the FIFOp and FIFOp2 modules into the document, I somehow exchanged
"Get" and "Put" throughout the text.  I have corrected the document on the Web site.
Thank you for pointing out the error.  I hope whenever anyone finds something on
the Web site that seems to make no sense, he or she will ask me about it.

The FIFOp module and FIFOp2 modules make no sense to me either.  I will investigate.

Hello, I was reading about prophecy variables in the paper Hiding, Refinement, and Auxiliary Variables" and I have to admit I'm mystified as to what the def of module FIFO2 is trying to say


Why is GetP effectively carrying out a Put action? While I can see how SpecP might implement Spec I don't see how \EE p: SpecP is equivalent to Spec
