Information in this documentation applies to all supported operating systems and architectures unless otherwise specified.
This documentation uses the following conventions:
Notational Conventions
THIS TYPE | Indicates statements, data types, directives, and other language keywords. Examples of statement keywords are WRITE, INTEGER, DO, and OPEN. |
this type | Indicates command-line or option arguments, new terms, or emphasized text. Most new terms are defined in the Glossary. |
| Indicates a example code. |
| Indicates what you type as input. |
This type | Indicates menu names, menu items, button names, dialog window names, and other user-interface items. |
File > Open | Menu names and menu items joined by a greater than (>) sign indicate a sequence of actions. For example, "Click File > Open" indicates that in the File menu, click Open to perform this action. |
{value | value} | Indicates a choice of items or values. You can usually only choose one of the values in the braces. |
[item] | Indicates items that are optional. Brackets are also used in code examples to show arrays. |
item [, item ]... | Indicates that the item preceding the ellipsis (three dots) can be repeated. In some code examples, a horizontal ellipsis means that not all of the statements are shown. |
Windows* OS Windows operating system | These terms refer to all supported Microsoft* Windows* operating systems. |
Linux* OS Linux operating system | These terms refer to all supported Linux* operating systems. |
OS X* OS X operating system | These terms refer all supported OS X* and Mac OS* X operating system software. |
Microsoft Visual Studio* | An asterisk at the end of a word or name indicates it is a third-party product trademark. |
compiler option | This term refers to Windows* OS options, Linux* OS options, or OS X* options that can be used by the compiler to compile applications. |
| Conventions Used in Compiler Options | |
/option or | A slash before an option name indicates the option is available on Windows OS. A dash before an option name indicates the option is available on Linux OS* and OS X* systems. For example: |
/option:argument or | Indicates that an option requires an argument (parameter). For example, you must specify an argument for the following options: |
/option:keyword or | Indicates that an option requires one of the keyword values. |
/option[:keyword ] or | Indicates that the option can be used alone or with an optional keyword. |
option[n] or option[:n] or option[=n] | 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. |
option[-] | Indicates that a trailing hyphen disables the option; for example, /Qglobal_hoist- disables the Windows OS option /Qglobal_hoist. |
[no]option or | Indicates that "no" or "no-" preceding an option disables the option. For example: |
| Conventions Used in Language Reference | |
This color | Indicates extensions to the Fortran 2003 and Fortran 2008 Standards. These extensions (non-standard features) may or may not be implemented by other compilers that conform to the language standard. |
Intel Fortran | This term refers to the name of the common compiler language supported by the Intel® Fortran Compiler. |
Fortran | This term refers to language information that is common to previously supported Fortran standards, Fortran 2003, and Intel Fortran. |
Standard Fortran | This term refers to language information that is common to ANSI/ISO Fortran 95, ANSI/ISO Fortran 90, and Intel Fortran. |
Fortran 95 | This term refers to language features specific to ANSI/ISO Fortran 95. |
Fortran 2003 | This term refers to language features specific to ANSI/ISO Fortran 2003. |
Fortran 2008 | This term refers to language features specific to ISO/IEC 1539-1:2010 (Fortran 2008). |
integer | This term refers to the INTEGER(KIND=1), INTEGER(KIND=2), INTEGER (INTEGER(KIND=4)), and INTEGER(KIND=8) data types as a group. |
real | This term refers to the REAL (REAL(KIND=4)), DOUBLE PRECISION (REAL(KIND=8)), and REAL(KIND=16) data types as a group. |
REAL | 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. |
complex | This term refers to the COMPLEX (COMPLEX(KIND=4)), DOUBLE COMPLEX (COMPLEX(KIND=8)), and COMPLEX(KIND=16) data types as a group. |
logical | This term refers to the LOGICAL(KIND=1), LOGICAL(KIND=2), LOGICAL (LOGICAL(KIND=4)), and LOGICAL(KIND=8) data types as a group. |
< Tab> | This symbol indicates a nonprinting tab character. |
^ | This symbol indicates a nonprinting blank character. |
Platform Labels
A platform is a combination of operating system and central processing unit that provides a distinct environment in which to use a product (in this case, a computer language). An example of a platform is Microsoft* Windows* OS on processors using IA-32 architecture.
In this documentation, information applies to all supported platforms unless it is otherwise labeled for a specific platform (or platforms).
These labels may be used to identify specific platforms:
L*X | Applies to Linux* OS on processors using IA-32 architecture and and Intel® 64 architecture. |
M*X | Applies to OS X* and Mac OS* X operating system software on processors using IA-32 architecture and Intel® 64 architecture. |
W*S | Applies to Microsoft Windows* OS on processors using IA-32 architecture and Intel® 64 architecture. |
i32 | Applies to 32-bit operating systems on IA-32 architecture. |
i64em | Applies to 32-bit operating systems on Intel® 64 architecture and Intel® Many Integrated Core Architecture (Intel® MIC Architecture). |
i64em_mic | Applies to 32-bit operating systems on Intel® 64 architecture, targeting Intel® Many Integrated Core Architecture (Intel® MIC Architecture). |
