Dialects in Fortran Wiki

In some sense, there are dialects within the Fortran standards
themselves, including [[Free form layout|free form]]
and [[Fixed form layout|fixed form]] as well as
[[implicit none]] and other variations of the [[implicit]]
statement.
Several independent dialects of Fortran have also been
created over the years, including:
* [[EGTRAN]] (<em>Eg</em>don For<em>tran</em>),
 a dialect of [[FORTRAN II]] (1965)
* [[RATFOR]]---Rational Fortran [[Fortran 66-77]] (1974)
* [[IFTRAN]]---a Structured Extension of Fortran [[Fortran 66-77]] (~1974)
* [[ELF90]]---Essential Lahey Fortran 90
* [[F]]---a selected subset of [[Fortran 95]]
* [[Parametric Fortran]] -- a Fortran program-generator generator that can 
produce extensions of Fortran
* [[Modeling penthouse discussion#NeoFortran|NeoFortran]]
