Chapitre 7 Character Handling and Logic

This section describes the facilities for handling non-numerical data in Fortran. Character data are actually present in almost all programs, if only in the form of file names and error messages, but the facilities for character manipulation are now quite powerful. The logical data type is even more indispensable since a logical expression is used in every IF statement.
