Intel® Fortran is fully compliant with the ISO/IEC 1539:1997 Fortran language standard (Fortran 95). Intel Fortran also fully supports programs that conform to the earlier standards Fortran 90, FORTRAN 77 and FORTRAN IV (FORTRAN 66.) In some cases, compiler options may need to be specified to enable support of behavior that was different in earlier versions of the Fortran standard.
The Intel Fortran Compiler supports many features that are new to the latest revision of the Fortran standard, Fortran 2003 (ISO/IEC 1539:2004 ). Additional Fortran 2003 features will appear in future versions. Fortran 2003 features supported by the current version 10.1 compiler include:
- The Fortran character set has been extended to contain the 8-bit ASCII characters ~ \ [ ] ` ^ { } | # @
- Names of length up to 63 characters
- Statements of up to 256 lines
- Square brackets [ ] are permitted to delimit array constructors instead of (/ /)
- A named PARAMETER constant may be part of a complex constant
- Allocatable components of derived types
- ASYNCHRONOUS attribute and statement
- BIND(C) attribute and statement
- PROTECTED attribute and statement
- VALUE attribute and statement
- VOLATILE attribute and statement
- INTENT attribute for pointer objects
- Reallocation of allocatable variables on the left hand side of an assignment statement when the right hand side differs in shape or length (requires option "assume realloc_lhs")
- In all I/O statements, the following numeric values can be of any kind: UNIT=, IOSTAT=
- FLUSH statement
- WAIT statement
- ACCESS='STREAM' keyword for OPEN
- ASYNCHRONOUS keyword for OPEN and data transfer statements
- ID keyword for INQUIRE and data transfer statements
- POS keyword for data transfer statements
- PENDING keyword for INQUIRE
- The following OPEN numeric values can be of any kind: RECL=
- The following READ and WRITE numeric values can be of any kind: REC=, SIZE=
- The following INQUIRE numeric values can be of any kind: NEXTREC=, NUMBER=, RECL=, SIZE=
- Recursive I/O is allowed in the case where the new I/O being started is internal I/O that does not modify any internal file other than its own
- IEEE Infinities and NaNs are displayed by formatted output as specified by Fortran 2003
- In an I/O format, the comma after a P edit descriptor is optional when followed by a repeat specifier
- Rename of user-defined operators in USE
- INTRINSIC and NON_INTRINSIC keywords in USE
- IMPORT statement
- Allocatable dummy arguments
- Allocatable function results
- COMMAND_ARGUMENT_COUNT intrinsic
- GET_COMMAND intrinsic
- GET_COMMAND_ARGUMENT intrinsic
- GET_ENVIRONMENT_VARIABLE intrinsic
- IS_IOSTAT_END intrinsic
- IS_IOSTAT_EOR intrinsic
- MOVE_ALLOC intrinsic
- NEW_LINE intrinsic
- SELECTED_CHAR_KIND intrinsic
- The following intrinsics take an optional KIND= argument: ACHAR, COUNT, IACHAR, ICHAR, INDEX, LBOUND, LEN, LEN_TRIM, MAXLOC, MINLOC, SCAN, SHAPE, SIZE, UBOUND, VERIFY
- ISO_C_BINDING intrinsic module
- ISO_FORTRAN_ENV intrinsic module
Please see the compiler release notes for an updated list.
Intel Fortran also includes a number of extensions to Fortran 95, as well as command-line options that allow you to override the default actions of the compiler.
