Perhaps the most significant development in the early history of FORTRAN was the decision by the American Standards Association (now ANSI) to form a committee to develop an "American Standard Fortran." The resulting two Fortran standards, approved in March 1966, defined two
languages, FORTRAN (based on FORTRAN IV, which had served as a de facto standard), and Basic FORTRAN (based on FORTRAN II, but stripped of its machine-dependent features). The FORTRAN defined by the first standard became known as FORTRAN 1966 (although many continued to refer to it as FORTRAN IV, the language upon which the Fortran standard was largely based). FORTRAN 66 effectively became the first "industry-standard" version of FORTRAN. FORTRAN 66 included:

* Fortran Main program, Fortran SUBROUTINE, Fortran FUNCTION, and Fortran BLOCK DATA Fortran program units
* Fortran INTEGER, Fortran REAL, Fortran DOUBLE PRECISION, Fortran COMPLEX, and Fortran LOGICAL Fortran data types
* Fortran COMMON, Fortran DIMENSION, and Fortran EQUIVALENCE Fortran statements
* Fortran DATA statement for specifying initial Fortran values
* Fortran Intrinsic and Fortran EXTERNAL (e.g., Fortran library) Fortran functions
* Fortran Assignment statement
* Fortran GOTO, Fortran assigned GOTO, and Fortran computed GOTO Fortran statements
* Fortran Logical IF and Fortran arithmetic (Fortran three-way IF) Fortran arithmetic IF statements
* Fortran DO loops
* Fortran READ, Fortran WRITE, Fortran BACKSPACE, Fortran REWIND, and Fortran ENDFILE statements for Fortran sequential I/O
* Fortran FORMAT statement
* Fortran CALL, Fortran RETURN, Fortran PAUSE, and Fortran STOP [[Fortran statements
* Fortran Hollerith constants in Fortran DATA and Fortran FORMAT statements, and as actual Fortran arguments to Fortran procedures
* Fortran Identifiers of up to six Fortran characters in length
* Fortran Comment lines
