Same thing but you have 2 identical programs so people with brains refer to the uniquely identified processes.

Trivially so, just not trivial to write down in Text Post format.

This is Process notation, not functions.

Same Proof as Turing's.
Just because YOU'RE too stupid to know anything about computers.
Halt is not a pure function, Turing proved the 1st Process Deadlock Proof!
But nobody in SCI.MATH or SCI.LOGIC with their MATHS DEGREES even knows what a DEADLOCK IS!

this is WAY ABOVE GEORGE'S HEAD...
I think a HALTING PROGRAM will work with PROGRAM TRANSITIONS.
You Start with:
10 PRINT "FINISH"
and you CONSTRUCT ANY OTHER HALTING PROGRAM
with ALLOWABLE TRANSITIONS.

But like I said... WAAAAY Above George's head and all the *Maths Grads* who studied LOGIC LITERATURE because ART HISTORY DEGREE was full!
