Printing a Fortran Array with write - Jason Blevins.

We see that Fortran 77 follows the rounding rule that digits 0-4 are rounded downwards while 5-9 is rounded upwards. In this example each write statement used a different format statement. But it is perfectly fine to use the same format statement from many different write statements. In fact, this is one of the main advantages of using format.

Fortran - File Input Output - Tutorialspoint.

The contents of a FORMAT statement are a simple command language imbedded within Fortran. In fact, problems with the FORMAT are often not detected until execution of the program because the format instructions between the parentheses of the FORMAT statement are not actually interpreted until execution time. Always realize that a FORMAT does not really exist in isolation. It is tightly coupled.

I'm working.

Challenge

Fortran 77, by default, includes a newline after every write statement. This can be a problem if you want to print a number of elements on the same line, but you don’t know how many elements there will be at compile time. Specifically, if you want to print a matrix or two-dimensional array but you don’t know the dimensions, you probably want to do something like the following.

Fortran 77 Language Reference: 4 - Statements.

Each Fortran statement must have a line to itself (or more than one line if necessary), but the first six character positions on each line are reserved for statement labels and continuation markers. Since the statements in this example need neither of these features, the first six columns of each line have been left blank. The PROGRAM statement gives a name to the program unit and declares.

A FORTRAN 77 statement may be up to 40 lines long! Columns 7-72 contain the FORTRAN instructions. Instructions may be placed freely anywhere within this area. Indentation was a good idea in FORTRAN 77 just as it is now in FORTRAN 90. Columns 73-80 are ignored by the compiler and may be used by the programming for any desired purpose. In the days when programs were saved on decks (yes, I said.

Fortran 77 Tutorial - Stanford University.

A Fortran format specification is a list of format elements describing the variable format. the user can output text using the WRITE statement. Apostrophe editing will be accepted in the FMT subop associated with the READ statement, but will be ignored on input. That is, on input the format description xxxxx will have the effect of directing SST to ignore the next five characters. The same.

Solution

Note: the fixed format source of Fortran 77 is an obsolescent feature of Fortran 95. It must be repaced by the new free format. 4.5 Comments. The letter 'C' or an asterisk in column one causes the compiler to ignore the rest of the line, which may therefore be used as a comment to provide information for anyone reading the program. 4.6 A simple program. The following example uses the Fortran.

The Fortran language is still evolving; Fortran77 is an internationally agreed standard to which nearly all current compilers conform, but there is now a revised standard, Fortran90, which has been agreed but which has not yet been widely implemented. However, many compilers, including that available on this machine, already incorporate some of the new features of the Fortran90 standard as.
