=Preface=
The goal of this Fortran tutorial is to give a quick introduction to the most common features of the Fortran 77 programming language. A companion tutorial introduces the key enhancements found in Fortran 90. It is not a complete reference! Many details have been omitted. The presentation focuses on scientific computations, mainly linear algebra. The outline of this tutorial was inspired by the book "Handbook for Matrix Computations" by T.F. Coleman and C. Van (contracted; show full)The last type is character constants. These are most often used as an array of characters, called a string. These consist of an arbitrary sequence of characters enclosed in apostrophes (single quotes):

      'ABC'
      'Anything goes!'
      'It is a nice day'
Strings and character constants are case sensitive. A problem arises if you want to have an apostrophe in the string itself. In this case, you should double the apostrophe:


<pre>⏎
      'It''s a nice day'
</pre>⏎
⏎
==Expressions==

The simplest non-constant expressions are of the form

      operand operator operand
and an example is

      x + y
