List of Names
- Language type:
FORTRAN (from FORmula TRANSlation) is one of the oldest programming
languages. Originally developed in the
late 1950s, FORTRAN has moved through many
versions and is still popular even today.
FORTRAN is characterized by its good support
for mathematics, especially floating-point
computation, its lack of modular programming
structures, and implicit declarations,
and odd control-flow constructs. FORTRAN
is normally case-insensitive. In older
versions of the language, the
position of text on lines was significant;
Fortran90 and later versions support free-form
FORTRAN has had many versions over the
years, some of the
most popular being: FORTRAN I,
FORTRAN II, FORTRAN IV, FORTRAN 77,
and Fortran90. The current standard
is Fortran 95 (ISO/IEC 1539-1), and it
includes many modern structured programming
features in a traditional Fortran
specialized and parallel-processing
versions of FORTRAN have also been created.
John Backus, IBM, 1954-57

FORTRAN has long been a language of choice
for complex scientific calculations,
engineering models, statistics, and signal
processing. Its simple code structure and
lack of dynamic data structures make it
highly amenable to compiler optimization
and targetting to special hardware (eg.
Every few years, somebody predicts the imminent
death of FORTRAN, and it never happens.
