This text investigates the core principles of the Fortran 77 programming language with a specific emphasis on the implementation of structured programming techniques. Loren P. Meissner provides a comprehensive instructional framework designed to transition programmers from older, unstructured coding habits to the more disciplined, modular approach required by the Fortran 77 standard. The book serves as both a manual for language syntax and a pedagogical guide for writing maintainable, efficient scientific code.

Experts and educators recognize this text as a foundational resource for understanding the transition to structured programming within the Fortran ecosystem. Readers frequently note the technical density of the prose, which is tailored for students and professionals requiring a rigorous grasp of legacy computational standards.
