I found this an enjoyable read. I also have Wilkinson, both text and Algol book, which I used many years ago to write a fortran eigenvalue/vector routine. Worked very nicely. Done in VAX fortran and showed me that having subscript checking on added 30% to the run time.

I wonder what the bounds-check overhead looks like on a modern machine for that code?
