2nd Edition
Classical Fortran Programming for Engineering and Scientific Applications, Second Edition
Classical FORTRAN: Programming for Engineering and Scientific Applications, Second Edition teaches how to write programs in the Classical dialect of FORTRAN, the original and still most widely recognized language for numerical computing. This edition retains the conversational style of the original, along with its simple, carefully chosen subset language and its focus on floating-point calculations.
New to the Second Edition
- Additional case study on file I/O
- More about CPU timing on Pentium processors
- More about the g77 compiler and Linux
With numerous updates and revisions throughout, this second edition continues to use case studies and examples to introduce the language elements and design skills needed to write graceful, correct, and efficient programs for real engineering and scientific applications. After reading this book, students will know what statements to use and where as well as why to avoid the others, helping them become expert FORTRAN programmers.

"I enjoyed this book a great deal, and I recommended it highly. Articulate and unambiguous, Kupferschmid can be strongly opinionated. Whether in agreement or with occasional skepticism, I found his ideas worthy of thoughtful consideration. I suggest that scientists and engineers regard them in that light as well."
