Thanks. I had examined that super-long document twice before, but after reading your reply, I went through it super slow and found the relevant section, which I shall post below so nobody else need read through that long document for 12C related info...

Now I need to know when to Press ENTER. Maybe that's clear to some people, but not to me. I can complete steps 01 to 06 without pressing ENTER, but I stop at step 07.

Also what is step 27 “Rv”? No such button exists on the 12CP!

Next, what does STO with a + or - before the number mean? I press CHS before that number??

Next, isn’t “33 x<->y” incorrect? I see a white marked “x><y” key and then “x<=y” in blue, but there is no x<->y key!

All said, I don’t know how to key this in. Do you?
