Fortran 90 for the Fortran 77 Programmer
This tutorial is written in order to ease the transition from the very common and popular programming language Fortran 77 to the more modern Fortran 90. It is required that the reader is knowledgeable in Fortran 77. Topics covered include: Notables in the transition from Fortran 77 to Fortran 90, Specifications, The layout of a program, Control statements, Program units, Keyword arguments and default arguments, Recursion, Generic routines, The use of arrays and array sections, Pointers, The new precision concept, Additional problems at the transition, Use of program libraries, Peculiarities in the language Fortran 90, Status of Fortran 95 and Different Fortran standards.
