This handbook serves as the definitive technical reference for the Fortran 90 programming language, providing a comprehensive explanation of its ANSI/ISO standards. The authors, Jeanne C. Adams and Walter S. Brainerd, utilize their deep expertise in language development to detail the syntax, semantics, and structural rationale behind the Fortran 90 specification. By organizing the material logically, the text provides a framework for both learning the language's new features and implementing them effectively in computational environments.

Experts and practitioners recognize this volume as a foundational reference for the Fortran 90 standard. Readers frequently note the technical density of the prose, which makes it a reliable resource for developers requiring precise information on language specifications.
