JABS Portability Function: Returns an absolute value.
JDATE Portability Function: Returns an 8-character string with the Julian date in the form "yyddd". Three spaces terminate this string.
JDATE4 Portability Function: Returns a 10-character string with the Julian date in the form "yyyyddd". Three spaces terminate this string.
JNUM Elemental Intrinsic Function (Specific): Converts a character string to an INTEGER(4) value. This function cannot be passed as an actual argument.
KILL Portability Function: Sends a signal to the process given by ID.
KIND Inquiry Intrinsic Function (Generic): Returns the kind parameter of the argument.
KNUM Elemental Intrinsic Function (Specific): Converts a character string to an INTEGER(8) value.
LASTPRIVATE Parallel Directive Clause: Provides a superset of the functionality provided by the PRIVATE clause. It declares one or more variables to be private to an implicit task, and causes the corresponding original variable to be updated after the end of the region.
LBOUND Inquiry Intrinsic Function (Generic): Returns the lower bounds for all dimensions of an array, or the lower bound for a specified dimension.
LCOBOUND Inquiry Intrinsic Function (Generic): Returns the lower cobounds of a coarray.
LCWRQQ Portability Subroutine: Sets the value of the floating-point processor control word.
LEADZ Elemental Intrinsic Function (Specific): Returns the number of leading zero bits in an integer.
LEN Inquiry Intrinsic Function (Generic): Returns the length of a character expression.
LEN_TRIM Elemental Intrinsic Function (Generic): Returns the length of the character argument without counting trailing blank characters.
LGE Elemental Intrinsic Function (Generic): Determines if a string is lexically greater than or equal to another string, based on the ASCII collating sequence, even if the processor's default collating sequence is different. In Intel® Fortran, LGE is equivalent to the (.GE.) operator.
LGT Elemental Intrinsic Function (Generic): Determines whether a string is lexically greater than another string, based on the ASCII collating sequence, even if the processor's default collating sequence is different. In Intel® Fortran, LGT is equivalent to the > (.GT.) operator.
LINEAR Clause Parallel Directive Clause: Specifies that all variables in a list are private to a SIMD lane and that they have a linear relationship within the iteration space of a loop.
LLE Elemental Intrinsic Function (Generic): Determines whether a string is lexically less than or equal to another string, based on the ASCII collating sequence, even if the processor's default collating sequence is different. In Intel® Fortran, LLE is equivalent to the (.LE.) operator.
LLT Elemental Intrinsic Function (Generic): Determines whether a string is lexically less than another string, based on the ASCII collating sequence, even if the processor's default collating sequence is different. In Intel® Fortran, LLT is equivalent to the < (.LT.) operator.
LNBLNK Portability Function: Locates the position of the last nonblank character in a string.
LOC Inquiry Intrinsic Function (Generic): Returns the internal address of a storage item. This function cannot be passed as an actual argument.
%LOC Built-in Function: Computes the internal address of a storage item.
LOCK and UNLOCK Statements: A LOCK statement causes a lock variable to become locked by an image. An UNLOCK statement causes the lock variable to become unlocked. They take the following forms:
LOG Elemental Intrinsic Function (Generic): Returns the natural logarithm of the argument.
LOG_GAMMA Elemental Intrinsic Function (Generic): Returns the logarithm of the absolute value of the gamma function of the argument.
LOG10 Elemental Intrinsic Function (Generic): Returns the common logarithm of the argument.
LOGICAL Function Elemental Intrinsic Function (Generic): Converts the logical value of the argument to a logical value with different kind parameters.
LONG Portability Function: Converts an INTEGER(2) argument to INTEGER(4) type.
LOOP OpenMP* Fortran Compiler Directive: Specifies that the iterations of the associated loops can execute concurrently. This feature is only available for ifx.
LOOP COUNT General Compiler Directive: Specifies the iterations (typical trip count) for a DO loop.
LSHIFT Elemental Intrinsic Function (Generic): Shifts the bits in an integer left by a specified number of positions. This is the same as specifying ISHFT with a positive shift.
LSTAT Portability Function: Returns detailed information about a file.
LTIME Portability Subroutine: Returns the components of the local time zone time in a nine-element array.
