Block and statements, with optional and clauses, to provide improved language support for structured programming loop extensions, including parameter expressions, negative increments, and zero trip counts , , and statements for improved I/O capability Direct-access file I/O statement, to override implicit conventions that undeclared variables are if their name begins with , , , , , or (and otherwise) data type, replacing Hollerith strings with vastly expanded facilities for character input and output and processing of character-based data statement for specifying constants statement for persistent local variables Generic names for intrinsic functions (e.g. also accepts arguments of other types, such as or ). A set of intrinsics () for lexical comparison of strings, based upon the ASCII collating sequence. (These ASCII functions were demanded by the U.S. Department of Defense, in their conditional approval vote.) A maximum of seven dimensions in arrays, rather than three. Allowed subscript expressions were also generalized.
