this book is great when working in the mainframe....this helped me so much... i was so confused when processing my programs... but this book guides you step to step...thanks This is the second edition of the first introductory textbook written for the FORTRAN 90 standard. It remains suitable for the novice scientific programmer, drawing on a larger number of examples and exercises in this new edition. This introductory chapter describes the evolution of the Fortran programming language and its new extensions.
