Chapter 2 Language Elements A FORTRAN program is a sequence of statements that, when executed in a specified order, process data to produce desired results. Because each program has different data needs, FORTRAN provides 11 data types for constants, variables, functions, and expressions. FORTRAN also provides three additional constant formats, which are extensions to the ANSI 77 standard. All are described in "Data Types" later in this chapter. Keywords, special characters, special symbols, symbolic names, and data make up the statements of a FORTRAN program. This chapter describes the elements of statements.
