That is why the first 5 columns are for the line number, and why the
line numbers increment by 10. A dropped deck could be run through the
sorter. New lines of code be added by punching a line number in between
the 10s so that a whole new deck didn't have to be key punched.
Was that key punch machine a 029? That seems familiar.

it once and all hell broke loose.--
I started out as the 084 card sorter operator, working grave yard shift.
