Here's a note for the good of the order.
The NYT gave details as to network coverage of the pope's visit to NYC in the following article, which helps to clear up what was pre-empted at the network level:
https://www.nytimes.com/1979/10/03/archives/itinerary-today-in-new-york-and-philadelphia-tv-coverage.htmlThe NYC stations gave more extensive coverage than the networks did. NBC started at 10:15 eastern while ABC and CBS started closer to 10:45. Network coverage likely ended in the neighborhood of 11:30 to noon.
So for the CBS games on the Eastern/Central feed, "Beat the Clock" aired as normal, approximately half of "Whew!" was pre-empted, and (per the FAQ at golden-road.net) a half-hour rerun of TPIR from 1977 was used to fill that slot.
For the "Whew!" episode guide, the celebrity episodes indeed start at #134 on 11-5-1979. All airdates and non-airdates (due to "Magazine" or holiday programming) should now be resolved at least until March 1980, when we have the anomalous Betty White/Richard Kline week that
TV Guide only listed for three episodes. Time will tell whether it was a shorter week or the listings were wrong...
