Fortran II was great.

Anyways, the best compiler ever written was MNF. Minnesota Fortran. You
had to love the post mortem dumps. It was a breeze debugging college
students computer programs, they would come up to your desk with a
printed listing and run of the program, and you would point at the
post mortem dump and basically repeat to the student exactly what
was printed, while simultaneously pointing at the output.. "hmm, says
here it stopped on line XXX, in subroutine YYY, and this is what the
variables were at that time, so, what was your question again?"
