FORTRAN is almost as easy to learn as BASIC, and there is much evidence
to show that it is still a viable language for programs of any complexity.
Outside the field of commercial data processing, where COBOL reigns
supreme, there is no doubt that the majority of large systems are
implemented in FORTRAN. This is particularly true of simulators which of
course have much in common with simulation games.

Game Programming (1984)
Games & Fun in FORTRAN
A collection of source code listings of small games & programs in
FORTRAN 77, mostly ports of
BASIC type-in programs:
You have access to a real computer? There is a
FORTRAN 77 compiler available!
More FORTRAN Games
Slightly more complex text games, written in FORTRAN 77:
- The Oregon Trail
-- port of the BASIC text game from 1978 to FORTRAN 77
-- robotfindskitten for 32-bit DOS
And even more FORTRAN games
with available source code.
Random Numbers in FORTRAN 77
The ANSI FORTRAN 77 standard does not include any pseudo-random
number generator (PRNG). Most compilers provide extensions. In any case,
we can link PRNG procedures written in FORTRAN 77:
- ACORN -- Additive Congruential Random Number Generator
- Mersenne Twister -- FORTRAN 77 implementation
- Park-Miller -- minimum standard pseudo-random number generator
- RANLUX -- high-quality random number generator
In Fortran 90, we have access to the intrinsic subroutines
Computer Graphics in FORTRAN 77
Libraries to draw graphics to screen:
- EGGX/ProCALL -- free X11 graphics library for C and FORTRAN 77
- Alfred -- the MAD computer program
- Ray Casting -- basic 2.5-D engine for X11
- Shuttle -- software renderer ported from GW-BASIC
Early Computer Games in FORTRAN
There are many examples of early computer games and simulations originally
written in or later ported to FORTRAN:
(1959 -- 1962) in FORTRAN and IBM 7090 macro assembler (FAP), also
known as A Chess Playing Program for the IBM 7090 Computer.
The first computer program to play chess convincingly.
- The Sumerian Game
(1964) in FORTRAN Assembly Program (FAP), by William McKay and Mabel Addis for
the IBM 7090 time-shared mainframe. The FOCAL port of 1968 is known as
King of Sumeria or The Sumer Game, the BASIC port of
1973 as Hamurabi. The BASIC version was converted to
FORTRAN IV in 1979
(1966), a business simulation developed by Walter L. Brown at University
(1970), a chess engine in FORTRAN IV, by James J. Gillogly.
- Aaron Marcus’ Cybernetic Landscapes
(1971 -- 1973), a FORTRAN IV program for displaying a virtual reality
environment on an
- Willie Crowther’s Colossal Cave Adventure
(1975 -- 1977) in FORTRAN IV on PDP-8/10/11 and other systems. Later
ported to FORTRAN 77.
(1974), a horse race simulation in FORTRAN IV, by Ron Morgan and Kirk
(1978) on PDP-11, DEC VAX, IBM System/370, and other platforms,
by Bob Supnik. More or less the public domain version of the original
- Chris Crawford’s
(1976) on IBM 1130.
- Ken Thompson’s Space Travel
(1976) in FORTRAN IV on GE 635/GECOS -- the game that brought mankind
- Walter Bright’s Empire
(1978) in FORTRAN IV on PDP-10/11, DEC VAX, and others.
- Lunar Lander,
several FORTRAN ports.
- Star Trek and
Super Star Trek
on PDP-11, CDC 6600, Xerox Sigma 7, DEC VAX, and many more.
(1979), a real-time multi-player space battle game in FORTRAN IV
for DEC PDP-10.
- Hunt the Wumpus
(several FORTRAN ports).
- Bill Wolpert’s Mystery Mansion
(1978 -- 1981), an early text adventure for HP 1000 and
HP 3000 minicomputers.
a multi-user space battle game in FORTRAN IV for CDC Cyber, by
- Castlequest (1980),
a parser adventure by Michael S. Holtzman and Mark Kershenblatt in
- Kong/Lode Runner
(1981) on Prime 550 and DEC VAX.
- Chess, Tic Tac Toe, Minefield, and a few
more games developed at the
University of Toronto.
(1982) in FORTRAN 77, by U.S. National Institute of Standards and
(1983), a U.S. military communications-oriented war game, developed by
the Joint Telecommunications Staff Officers’ Course at Keesler Air
- Chris Pirih’s Ski (1985)
for VAX VMS, the text-based predecessor of SkiFree.
- Remake of Battle Zone
(1986) by Justin S. Revenaugh for Apollo Domain/OS, using the GPR graphics
library. The game was later ported as XBZONE to X11.
Apparently, the source archive
xbzone.tar.Z is lost. Todd
W. Mummert recreated the game in C as
for X11/Xaw (1990).
