I have seen ICT punches labelled this way. There is one here where "X" and

I think the one I own is labelled....
I've only ever seen them called
"12" and "11" for the top and next
rows respectively. For example, the card code listing on the IBM 360
"green card" shows them that way (e.g., A is 12-1).
Same here. But it's not outside the range of possibility that *someone*
called them X and Y, although I don't know who did. Doug Jones doesn't
mention it.
Let's not forget the System/3 96-column cards.
BA8421 (sort of like
7-track
mag tape), with a really wacky way to combine the
columns to make 8-bit
bytes.
Univac, of course, had their own system with their double-45 column
system,
round holes and all.
