So if you were doing all 80 columns, you got two rows of characters. Some cards were printed with either a single 60 column legend across the top or with 60/20 columns in 2 rows. Locating the actual column when looking at the interpreter output without one of the 60 column printed legends was "interesting". In fact, you could program the interpreter to put the columns anywhere you wanted on the card--I think the 557 (which I used) could do 25 rows per card. There was at least one pre-war interpreter that would print only 45 columns. Cheers, Chuck
