Fortran 77 for Engineering and Scientists: With an Introduction to Fortran 90 by Stephen J. Chapman

Designed for science and engineering students in first-year undergraduate courses, this text explains FORTRAN in a way suitable for use on large projects, and it stresses the importance of detailed designing prior to programming. A top-down design technique is used to break the program up into logical chunks. The text highlights the use of sub-programs to implement individual portions, and stresses the importance of unit testing before the sub-programs are combined into the finished product. Finally, the book discusses the need to exhaustively test the final program with many different input data sets before it is released for use. Also covered are two facets of all programming environments: maintaining large amounts of legacy code, and the existence of sub-routine libraries to make some programming tasks easier.
