A quick check in bitsavers IBM collection seems to
reveal no
particular convention. ?For example, the 1620 Fortran II manual shows
no slashes through either the ohs or the zeroes.
Likewise, for IBM terminals, the dot-in-the-center is not consistent.
Some have, most do not.
I wonder if it was a RFQ feature.
