Upgrading to Fortran 90 [Paperback]

A comprehensive tutorial that relies mainly on a large number of short, but complete programming examples to illustrate the differences between the new language and traditional Fortran. The author gives thorough explanations of terminology and concepts which were not in general use before the release of the new standard. Readers are assumed to have a working knowledge of one of the earlier versions of Fortran, but otherwise no prior knowledge of Fortran 90 is assumed.In 1991, a new international standard for Fortran was released which contained specifications for a new version of the language known as Fortran 90. It provides for dramatic extensions to previous Fortran versions. This book is a comprehensive tutorial to Fortran 90 that relies mainly on a large number of short, but complete programming examples to illustrate the differences between the new language and traditional Fortran. The author gives thorough explanations of terminology and concepts which were not in general use before the release of the new standard. Readers are assumed to have a working knowledge of one of the earlier versions of Fortran, but otherwise no prior knowledge of Fortran 90 is assumed.1 Getting Ready.- 1.1 Overview of the Chapter.- 1.2 FORTRAN, FORTRAN 77, Fortran 90, Fortran.- 1.3 Fortran 90 Compared with FORTRAN 77.- 1.4 Fortran 90 Version of the Hello, World Program.- 1.5 Preview: Simple Extensions of FORTRAN 77.- 1.6 Preview: Array Operations.- 1.7 Preview: Sharing Data by Way of a Module.- 1.8 Preview: Module Subprograms.- 1.9 Preview: Derived Types.- 1.10 Preview: Pointers.- 1.11 Preview: Interface Blocks.- 1.12 Preview: Scoping Units.- 1.13 Terminology: Constant, Variable, Array.- 1.14 Conventions Used in Specifying Syntax.- 2 Laying the Foundation.- 2.1 Overview of the Chapter.- 2.2 Programmer-Chosen Names.- 2.3 Free Source Form.- 2.4 The General Form of a Main Program.- 2.5 Simple Type Declarations for Intrinsic Types.- 2.6 Specifying Initial Values in a Type Declaration.-lì
