[COFF] On having a slash

[Thomas Paulsen]

'Way back then, when dinosaurs strode the earth and System/360 reigned 
supreme, we were taught to slash our zeros and sevens (can't quite find 
the glyphs for them right now) in order to distinguish them from Oscars 
and Ones for the benefit of the keypunch girls...'

I  slash both zeros and sevens too.  With regards to the zero I learned it at the university in the 70ths, 
however I believe that slashing sevens I learned already in the school days(60ths) or even at home 
by my parents (50ths).
