Those of use who worked in Fortran understand these things... columns
73-80 were ignored by the compiler.  The normal use was to put line
numbers in there to help recovery when you dropped your card deck on the
floor and had to unshuffle things.  A diagonal line drawn across the
top of deck helped a lot, but it was good to have verification for the
marginal cases.

Kids today just don't have any culture at all...:)
