I'm not sure if this helps or not.

When i learned the fortran 77 standard, it utilized columns 7-72, anything in column 1 signified a comment, col 2-5 were reserved for labels, col 6 marked a continuation line, and columns 73-80 had significance I can't recall.  The strict layout had historical significance related to punch-cards, which I believe ran 80 columns wide.

The f90 standard I believe expanded the usable codespace to 132 columns, but I'm not sure exactly how that number became astandard.

I think the punch-card thing might be where the 80 column value comes from though.  I'm just not sure which is the chicken and which the egg.
