Thanks for the Article Steve, my last Fortran book I had in 1988 and it was extolling the virtues of F77 so perhaps a new one is in order as a new years present to myself!
I did notice in the blog items a few posts up from this latest article "Doctor Fortran in "Revert! Revert! The End (of the format) is Nigh!" is a broken link BTW.
