- Unless Mr Tate has a fairly restriced view of 'programs' I must say:
-
- "Surely you're joking Mr Tate?"...
-
- I DO hope my Unix instance never halts...so
- in fact most computer users see a program never halting EVERY SINGLE DAY,
- namely their favourite OS!!
- MOST sensible production programs are designed to NEVER EVER HALT unless
- explicitely told to do so (e.g. Unix 'halt'). By the way, the number of halting
- programs is probably vastly outnumbered by the number of non-halting programs.
- Or....??
