A variable can be defined with a Hollerith value through a DATA statement, an assignment statement, or a READ statement. • The number of characters (n) in the Hollerith constant must be less than or equal to g, the maximum.

In this tutorial we will emphasize standard ANSI. Fortran 77. Why learn Fortran? Fortran is the dominant programming language used in engineering applications. It is therefore important for engineering graduates to be able to read and modify Fortran code. From time to time, so-called experts predict that Fortran will rapidly
READ. The READ statement reads data from a file or the keyboard to items in the list. Note -. Use the TOPEN() routines to read from tape devices. See the Fortran Library Reference Manual.

A FORTRAN program generally consists of a main program and possibly several Fortran 77 is not a free-format language, but has a very strict set of rules for how the source code should be formatted. . reference the i'th element of array a by a(i).
decent compiler: • Read a user's program, stored in a file and containing instructions written in Fortran . This manual specifically documents the Fortran front end, which handles the program- ming language's The GNU Fortran compiler is the successor to g77, the Fortran 77 front end included in GCC prior to version 4.
