Notational Conventions

Indicates statements, data types, directives, and other language keywords. Examples of statement keywords are WRITE, INTEGER, DO, and OPEN.

Indicates command-line or option arguments, new terms, or emphasized text. Most new terms are defined in the Glossary.

Indicates a code example.

Indicates what you type as input.

Indicates menu names, menu items, button names, dialog window names, and other user-interface items.

Menu names and menu items joined by a greater than (>) sign to indicate a sequence of actions. For example, Click File > Open indicates that in the File menu, you would click Open to perform this action.

Indicates a choice of items or values. You can usually only choose one of the values in the braces.

Indicates items that are optional. Brackets are also used in code examples to show arrays.

Indicates that the item preceding the ellipsis (...) can be repeated. In some code examples, a horizontal ellipsis means that not all of the statements are shown.

This term refers to the name of the common compiler language supported by the Intel® Fortran Compiler.

These terms refer to all supported Microsoft Windows* operating systems.

These terms refer to all supported Linux* operating systems.

These terms refer to all supported macOS* operating systems.

An asterisk at the end of a word or name indicates it is a third-party product trademark.

This term refers to Linux*, macOS*, or Windows* options, which are used by the compiler to compile applications.

The following conventions are used as shortcuts when referencing compiler option names in text:

• Many options have names that are the same on Linux*, macOS*, and Windows*, except that the Windows* form starts with an initial / and the Linux* and macOS* form starts with an initial -. Within text, such option names are shown without the initial character. For example, check.

• Many options have names that are the same on Linux*, macOS*, and Windows*, except that the Windows* form starts with an initial Q. Within text, such option names are shown as [Q]option-name.

  For example, if you see a reference to [Q]ip, the Linux* and macOS* form of the option is -ip and the Windows* form of the option is /Qip.

• Several compiler options have similar names except that the Linux* and macOS* forms start with an initial q and the Windows* form starts with an initial Q. Within text, such option names are shown as [q or Q]option-name.

  For example, if you see a reference to [q or Q]opt-report, the Linux* and macOS* form of the option is -qopt-report and the Windows* form of the option is /Qopt-report.

Other dissimilar compiler option names are shown in full.

A slash before an option name indicates the option is available on Windows*. A dash before an option name indicates the option is available on Linux* and macOS* systems. For example:

• Windows* option: /fast
• Linux* and macOS* option: -fast

Indicates that an option requires an argument (parameter). For example, you must specify an argument for the following options:

• Windows* option: /Qdiag-error-limit:n
• Linux* and macOS* option: -diag-error-limit=n

Indicates that an option requires one of the keyword values.

Indicates that the option can be used alone or with an optional keyword.

Indicates that the option can be used alone or with an optional value. For example, in /Qfnalign[:n] and -falign-functions[=n], the n can be omitted or a valid value can be specified for n.

Indicates that a trailing hyphen disables the option. For example, /Qglobal_hoist- disables the Windows* option /Qglobal_hoist.

Indicates that no or no- preceding an option disables the option. For example, in the Windows* option /[no]traceback, /traceback enables the option, while /notraceback disables it.

In the Linux* and macOS* option -[no-]global_hoist, -global_hoist enables the option, while -no-global_hoist disables it.

In some options, the no appears later in the option name. For example, -fno-alias disables the -falias option.

Indicates Intel extensions (non-standard features) that may or may not be implemented by other compilers. Features defined by the Fortran Standards or the OpenMP* Standards are shown in black.

This term refers to language information that is common to previously supported Fortran standards, Fortran 2008, and the Intel® Fortran Compiler.

This term refers to language information that is common to ANSI/ISO Fortran 95, ANSI/ISO Fortran 90, and Intel® Fortran.

This term refers to language features specific to ANSI/ISO Fortran 95.

This term refers to language features specific to ANSI/ISO Fortran 2003.

This term refers to language features specific to ISO/IEC 1539-1:2010 (Fortran 2008).

This term refers to the INTEGER(KIND=1), INTEGER(KIND=2), INTEGER (INTEGER(KIND=4)), and INTEGER(KIND=8) data types as a group.

This term refers to the REAL (REAL(KIND=4)), DOUBLE PRECISION (REAL(KIND=8)), and REAL(KIND=16) data types as a group.

This term refers to the default data type of objects declared to be REAL. REAL is equivalent to REAL(KIND=4), unless a compiler option specifies otherwise.

This term refers to the COMPLEX (COMPLEX(KIND=4)), DOUBLE COMPLEX (COMPLEX(KIND=8)), and COMPLEX(KIND=16) data types as a group.

This term refers to the LOGICAL(KIND=1), LOGICAL(KIND=2), LOGICAL (LOGICAL(KIND=4)), and LOGICAL(KIND=8) data types as a group.
