An Introduction to Programming with Fortran is a comprehensive introduction to Fortran, and is essential to the complete beginner who wants to learn the fundamentals of programming using a modern, powerful and expressive language; as well as those wanting to update their programming skills by making the move from earlier versions of Fortran. It contains lots of clear and simple examples highlighting the key language features of the most recent versions of Fortran Fortran 2003, 95 and 90. The authors also provide examples based on ISO TR 15580 and ISO TR 15581 as these are quite widely supported as well and cover the ISO TR on Enhanced Modules, which is of particular importance to large code suites. The examples used throughout the book highlight common problems that occur when programming, and give a solution in Fortran, producing a very effective, hands-on approach. Details of a variety of internet-based sources are also included, which will prove invaluable to those seeking further information and support.
