Topic: FORTRAN II


  
  Fortran programming language
FORTRAN was developed in the 1950-s by a team of IBM programmers and released in 1957.
FORTRAN knew an implicit typing, that means that variable names beginning with I, J, K, L, M, N were always integer and the rest were reals.
FORTRAN was developed by an IBM team lead by John W. Backus (see picture) and staffed with programmers like Sheldon F. Best, Harlan Herrick, Peter Sheridan, Roy Nutt, Robert Nelson, Irving Ziller, Richard Goldberg, Lois Haibt and David Sayre.

  Fortran - Wikipedia, the free encyclopedia
Fortran III was designed in 1958, allowing for inline assembler code; but it was never released because the portability concept of a high-level language would be lost.
Fortran 90 was a major revision, adding free source form, dynamic memory allocation, array operations, abstract data types, operator overloading, pointers, and modules to group related procedures and data together.
Fortran 95 was a minor revision, adding features for parallel programming from the High Performance Fortran dialect, such as user-defined pure and elemental functions, and the forall construct.

FORTRAN II During the field debugging period some shortcomings of the system design, which we had been aware of earlier but had no time to deal with, were constantly coming to our attention.
FORTRAN II was distributed in the spring o f 1958.
Even though the facilities of FORTRAN II permitted separate compilation of subroutines and hence eliminated the need to recompile an entire program at each step in debugging it, nevertheless compile times were long and, during debugging, the consider able time spent in optimizing was wasted.

 FORTRAN Notes
FORTRAN uses implicit typing, in which the type of a variable is determined by its first letter.
FORTRAN programs originally controlled access to sequential files on tape drives, that were such a prominent feature of mainframe computers, and often appeared in films, because they provided motion.
In FORTRAN 77 there is no way to delimit a block so that it can be used in the place of a single statement, as in C or Pascal.

Originally this was to have been Fortran 2000, but the perhaps inevitable delays in deciding its content meant that the schedule slipped and so it became Fortran 2003.

It is the plan of this proposed text to first introduce the student to Fortran 95, learn its syntax, and develop the important skills of good software design (which are generally independent of a specific language).
The choice of first introducing Fortran 95 is somewhat arbitrary but is based primarily on its being a more natural language for many scientists and engineers.

Fortran won the battle against Assembly language, the first in a series of battles to come, and was adopted by the scientific and military communities and used extensively in the Space Program and military projects.
FORTRAN II, III, IV and FORTRAN 66 ---------------------------------- FORTRAN II (1958) was a significant improvement, it added the capability for separate compilation of program modules, assembly language modules could also be 'linked loaded' with FORTRAN modules.
FORTRAN IV (1961) was a 'clean up' of FORTRAN II, improving things like the implementation of the COMMON and EQUIVALENCE statements, and eliminating some machine-dependant language irregularities.

 FORTRAN
The FORTRAN System has been developed to enable the programmer to state in a relatively simple language, resembling familiar usage, the steps of a procedure to be carried out by the 704 computer, and to obtain automatically from the 704 an efficient machine language program for this procedure.
The FORTRAN System is intended to reduce substantially the time required to produce an efficient machine language program for the numerical solution of a problem, and to relieve the programmer of a considerable amount of manual andquot;clericalandquot; work, minimizing the possibility of human error by relegating the mechanics of coding and optimization to the 704.
Fortran II permitted a program to be broken down into subprograms which could be tested and debugged separately.

 Fortran Summary
The development of FORTRAN paralleled the early evolution of compiler technology; indeed many advances in the theory and design of compilers were specifically motivated by the need to generate efficient code for FORTRAN programs.
FORTRAN IV was eventually released in 1962, first for the IBM 7030 ("Stretch") computer, followed by versions for the IBM 7090 and 7094.
Prior to FORTRAN 77, a number of preprocessors were commonly used to provide a friendlier language, while retaining the advantage that the preprocessed code could still be compiled on any machine with a standard FORTRAN compiler.

FORTRAN was developed at the IBM campus in south San Jose, lead by a development team including John W. Backus (whose name is attached to a form now used to describe computer languages).
Fortran is (probably) the only example of a widely-used, scientifically-oriented, computer language that has developed over almost 50 years.
Fortran is not case sensitive, so uppercase and lowercase letters are considered the same.

 Introduction
In April 1978 the American Standardization Committee ANSI approved a new standard for Fortran, it is well known with the name Fortran 77 in order to distinguish the new standard ANSI X3.9-1978 from the old ANSI X3.9-1966, which sometimes nowadays is called Fortran 66.
Fortran 77 was very welcome in that it increased the capabilities of writing Fortran programs in a structured way, and that it standardized many of the extensions that different manufacturers had put into their implementations of Fortran.
The Appendices 2 and 3 summarize Fortran 77 and the new facilities in Fortran 90, respectively.

 Dusty Decks » Blog Archive » The birth of the FORTRAN II subroutine
The original FORTRAN system (see here or here) had a variety of built-in library functions and allowed the programmer to write single-statement function statements, or to add additional library functions written in assembler, but there were no separately compiled FORTRAN subroutines or functions.
FORTRAN II was distributed in the spring of 1958.”
The ability to build Fortran programs out of independently-compilable modules and to have the ability to decompose into functions and subroutines using Fortran or any other tool that produced compatible code (usually the assembler, in those days) had an immense impact.

 Math 60 -- Notes Fortran 1
Fortran is not standardized completely; it can lead to messy code (especially in the older programming style); its compilers can be nightmares for developers; there are many local variants.
Some of the "supercomputers" have only two compilers available: C and Fortran, and the Fortran compiler is better optimized than the C compiler (i.e., runs codes faster because it is more efficient).
Fortran is not the savior, but it does a lot, and has the advantage of undergoing constant revision and upgrading in such a fashion that older code will continue to run with newer compilers with a minimum of touching up.

One should, however, consider that the features of Fortran have been tuned to scientific and numerical work, and that many of its deficiencies have been addressed in more recent versions.
For example, Fortran 95 has very short commands for performing mathematical operations on arrays which not only greatly improve program readability but also provide useful information to the compiler to enable it to vectorize operations.
For these reasons, Fortran is not often used outside scientific and engineering numerical work, but remains the language of choice for high performance numerical computing.
