What's to learn? The continuation column is the last column not used
for sequence numbers.

What standard? the old 3278 line supported up to 43 lines of 80
columns, and the 3278-5 supported 27x132, but those were two decades
ago. Starting with the 3290 there were more options, and in todays
world the old limits are only relevant if the installation management
wants them to be.

It must have been a long time ago, because ISPF has supported 160
column display modes since Old Man Noach cornered the market in gopher
wood.
